Installation and upgrade
Install permissions |
The installation process, for all components, requires a full administrator account (root account for Linux systems) for all operating systems. After installation, all of the LoadRunner Professional applications and components can run under a standard user account (an administrator account is not required), with UAC and DEP enabled. |
License update |
When upgrading to version 2020, you need to replace your current license to work with the upgraded LoadRunner Professional installation. If you are using the Community license, it is automatically replaced during LoadRunner Professional installation. For any other license, contact support to obtain a valid, compatible license. For more information, see |
Virtual environments |
The architectures provided by virtualization vendors are rapidly evolving. LoadRunner Professional is expected to function as designed in these changing environments, as long as the third-party vendor guarantees full compatibility of the virtualized environment with the LoadRunner Professional-approved hardware requirements. If you follow the LoadRunner Professional system requirements and support matrix to create the virtual machine, LoadRunner Professional will work correctly. Working on top of a virtual machine may require access to the virtualization server hardware/monitoring environment to ensure the virtualization server is not saturated; otherwise, this might obscure the virtual machine's measurements and lead to false results. |
Security - CA certificate |
From version 12.60, LoadRunner Professional uses an updated version of OpenSSL, which enforces additional constraints for secure communication. OpenSSL (from 1.1.x) requires that the basic constraints for a CA certificate include a confirmation that the certificate is a CA certificate. Upgrade: If you are upgrading from a version earlier than 12.60, and your CA certificate was created in an earlier LoadRunner version using any of the LoadRunner tools, you can no longer use these certificates because they do not include the required constraints. Use the LoadRunner Professional tools to create and install a new CA certificate and new TLS certificates on each LoadRunner Professional machine. For details, see Secure Communication with TLS (SSL). Organization's CA: If your CA certificate is provided by your organization, verify that the certificate includes the constraints described above. If the required constraints are not defined, your IT department should provide updated CA and TLS certificates to install on the LoadRunner Professional machines. To verify: Check that the constraint is defined for the CA certificate in the Basic Constraints extension, for example, Subject Type=CA or CA:TRUE (the constraint format varies, depending on how the certificate was accessed).

Virtual Table Server (VTS) upgrade |
|
Visual C++ installation |
Visual C++ 2013 Redistributable is no longer a prerequisite for LoadRunner Professional. Note that when using the Visual Studio 2013 IDE add-in, Visual C++ 2013 Redistributable is automatically installed when installing the IDE. |
Coexistence with UFT family |
|
Network Virtualization | Installation of the Network Virtualization for Linux package (NV4LG) is not currently supported on Ubuntu 18.04, due to NV Driver installation failure. |
Uninstall |
|
Microsoft Windows
Microsoft Windows 10 and Windows Server 2016
Default browser |
|
Windows Sockets (WinSock) |
Recording on Microsoft Edge browser is not supported for WinSock. |
Microsoft Windows 10 May 2019 Update (1903)
Docker |
Publishing a container port fails on Windows 10 1903. As a result, Dockerized load generators are not supported when using Windows 10 1903 edition. (Recommended OS: Windows Server 2019, build 17763) |
Permissions
License utility |
When running the License Utility with UAC enabled, LoadRunner Professional prompts you for administrator credentials. Resolution: Run the utility as administrator. |
Web scripts and IE ESC |
On a Window Server operating system when recording Web protocol scripts, or recording and replaying TruClient - Web scripts, it is recommended to disable Internet Explorer Enhanced Security Configuration (IE ESC). Resolution: In Windows 2012 R2, 2016, 2019, select Server Manager > Local Server > Internet Explorer Enhanced Security Configuration. |
Web scripts and DEP |
When recording a Web-based protocol script, the recording may fail in certain installations, if Data Execution Prevention (DEP) is enabled. Resolution: Disable DEP on your VuGen machine. For details, see Record a Vuser Script. |
Visual Studio |
When using Visual Studio and add-ins to create C# and VB .NET scripts, Visual Studio creates .NET assemblies that need to be registered in the system before their run. Registration of the .NET assembly requires administrative permissions. Resolution: Enable UAC and register the .NET assembly before running the test using one of these methods:
|
IP Wizard |
The IP Wizard does not function for a Limited user. Resolution: Run the IP Wizard with administrator permissions. The IP Wizard uses raw sockets to communicate with remote machines. Therefore, administrative privileges are required for opening and using raw sockets in socket-based communication. For more information, see http://msdn.microsoft.com/en-us/library/windows/desktop/ms740548%28v=vs.85%29.aspx. Alternatively, you can set the IP Wizard settings locally on the target machine. |
Load generator on Linux |
The network settings for load generators on Linux machines cannot be configured by a standard (non-administrator) user account. Resolution: When working on a Linux operating system, run lr_agent_settings with administrator permissions. |
Trusted sites |
If you open a Micro Focus site in the embedded browser and the site is not included in the trusted sites list, you will be prompted to add the site to the trusted site list. After adding the site, you may receive a Web site scripting error. Resolution: Close the error and continue working as you normally would. |
VuGen and protocols
For known issues in TruClient, see TruClient known issues.
DevWeb | From version 2020, the TruWeb protocol is renamed to DevWeb. When running Vusers for DevWeb/TruWeb scripts in LoadRunner Professional, they consume license capacity as part of your community license, or protocol license for Web - HTTP/HTML. |
Recording | When recording, if Microsoft User Experience Virtualization (UE-V) or Microsoft Application Virtualization (App-V) is enabled, it might block the LoadRunner Professional recording (hooking) mechanism and cause recording to fail. |
SSL |
|
Proxy settings |
|
Creating scenarios | When you use VuGen to create a scenario, if Controller is open (and was opened by double-clicking a .lrs scenario file), you will not be given the option to add the script to the current scenario, and Controller will be closed, losing any unsaved changes. |
DFE | Data Format Extensions (DFEs) are supported on Windows operating systems only. |
Replay - JSON | Parsing a long JSON in the Replay log, or a JSON file containing a long line, may cause a short delay when scrolling in the Replay log. |
Java |
|
C Vuser scripts | 64-bit replay for C Vuser scripts is not supported on Linux-based load generators. |
Web - HTTP/HTML |
|
VBScript |
Runtime errors generated during the replay of VBScript scripts may not be handled properly. It is recommended that you port existing VBScript scripts to C. Possible resolution: Enable the Continue on Error option in the Runtime settings. |
Conditional breakpoints | When adding a conditional breakpoint based on a parameter value, the value is not updated immediately. Therefore, in the script step that follows, the condition may be ignored even though the argument value has been updated. |
VTS |
When you stop a named VTS instance, the instance may continue to run until you restart the VTS Windows service, which will block you from creating an instance with the same name or port. Resolution: Restart the VTSService Windows service. For example, use the “net stop vtsservice” to stop the service, and “net start vtsservice” to restart it. |
Webtrace on Linux |
Webtrace is not supported with -proto tcp and -proto udp in the following Linux environments: RHEL 7, OEL 7. |
SAP UI Landscape XML | The SAP UI Landscape XML format for connection definitions is currently not supported. |
WinInet replay |
When using the WinInet replay engine, you may encounter the following error: "HttpSendRequest" failed, Windows error code=12002. Resolution: Change the default timeout setting for the WinInet replay engine. In the Registry Editor, open HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings, and change the default time (30 seconds) to 180 seconds: "SendTimeOut"=dword:0002bf20 "ReceiveTimeOut"=dword:0002bf20 |
Web Services |
When using the Import SOAP option to generate API web_services_call from a SOAP file, it is expected that the majority of the generated cases will be web_services_call. However, the actual results are mainly soap_request, and very few cases of web_services_call. |
Controller and load generators
Running scenarios | When using Controller with MI Listener, and Network Virtualization is enabled, you may encounter the following issues:
|
SiteScope monitor |
When using the SiteScope monitor, you cannot change the counters already saved with the scenario. Resolution: Remove all existing SiteScope counters, close the dialog box and re-add them. |
Network Virtualization and Service Virtualization
NV installation |
|
Licensing |
Network Virtualization usage is included with the LoadRunner Professional protocol licenses; network emulation and NV Insights do not require any additional license purchase. |
Linux |
|
Virtual Locations |
Analysis Summary reports and NV Insights show None as the Virtual Location name even though no groups with this name were defined in a LoadRunner Professional scenario. Resolution: See Software Self-solve knowledge base article KM03407056. |
Service Virtualization and SSL |
If a Service Virtualization server uses credentials for both SSL and monitors, then the Service Virtualization project cannot be correctly imported to a scenario. Resolution: Configure the Service Virtualization server to use credentials only for SSL. |
General
ALM integration |
If you have a slow connection from VuGen or Analysis to ALM, this may be because the VuGen or Analysis machine does not have access to the WAN, and so cannot verify the digital signature of the relevant files. Resolution: Download and import the certificates from https://support.globalsign.com/customer/portal/articles/1426602-globalsign-root-certificates using certmgr MMC until the issue is resolved (you might not need to import all the certificates). |
Scaling and zoom | Changing the display settings, to reset the display scale and zoom, is not supported for any LoadRunner Professional or LoadRunner Enterprise components. |
Non-English operating systems
Language pack installation |
If you install a language pack after you have already generated an Analysis session, you will not be able to open the session file (.lra). You can only open it on a machine with the same regional settings as the machine upon which it was generated. You can, however, open the raw results, the .lrr file. |
Untranslated items |
On non-English operating systems, several components may contain untranslated items, such as the Print Preview page in VuGen, log files, and installation screens. |
Chinese OS |
LoadRunner Professional cannot record a Vuser script for certain protocols if the LoadRunner Professional installation is on a Chinese operating system, and the installation path contains Chinese characters. |
Path names |
Path names cannot be in multi-byte format. |
Documentation
IE ESC |
When LoadRunner Professional is installed on a Windows Server operating system, Internet Explorer Enhanced Security Configuration (IE ESC) must be disabled in order to view Help Center content. It is enabled by default. Resolution: In Windows 2012 R2, 2016, 2019, select Server Manager > Local Server > Internet Explorer Enhanced Security Configuration. |
Trusted domains |
On certain machines with high level security settings, you need to trust the domain (admhelp.microfocus.com/lr, admhelp.microfocus.com/vugen, admhelp.microfocus.com/tc, admhelp.microfocus.com/pc) in order to view the Help Center. Resolution: Open the Help Center in IE, and accept the site as a trusted domain. Then you will be able to use the context sensitive and menu help from the product. |
Acrobat Reader |
On Windows 8.1 and later, disabling UAC may block Acrobat Reader from opening PDF files. Follow the Windows Help instructions to enable UAC and trust Acrobat. |
Local help on Chrome |
When opening the help locally in a Chrome browser, you cannot hide the message banner at the bottom of the screen. Clicking the Got it! button does not remove it. |
