--- | ---
Uninstall fails or freezes | This error can occur if uninstall does not complete successfully, takes a long time and seems to have frozen, or if does not appear in Add/Remove Programs. Reboot the machine and uninstall it again (unless it no longer appears in Add/Remove Programs). Alternatively, you can: Open a command prompt and run: <Host_installdir>\bin\HP.PC.PCS.Configurator.exe /CFG:..\dat\setup\lts\xml\Configurator.xml /G:Uninstall Delete OpenText Enterprise Performance Engineering Host from the Start menu.

To add the network server to your Trusted Sites: In the Control Panel, select Internet Options > Security. Click Trusted Sites and then click the Sites button. In the Trusted Sites dialog box, add the location of the network server where the component setup file is located, to the list of trusted sites.
Unable to install components from the installation directory | Make sure the user running the installation has sufficient permissions to launch executable files. Restart the machine and try again.

Unable to install Network Virtualization (NV) components | Windows SmartScreen prevents NVinstaller.exe from running and installing NV Components. Before proceeding with the NV installation, open HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer in the Registry Editor. Change the Value data for SmartScreenEnabled to "Off" to deactivate Windows SmartScreen.
Host silent installation stops after installing .NET Framework 4.8 | .NET Framework 4.8 replaces the .NET Framework 4.6.2 and earlier files. If there are any applications that are using the .NET Framework 4.6.2 or earlier files and are running during the installation of .NET Framework 4.8, you may need to restart your machine. If you are prompted to restart the machine, restart it before continuing the installation. Refer to the product documentation for more details.
A new user profile is created each time the product is installed | Each time OpenText Enterprise Performance Engineering is installed, a new user profile is created, even if the product was installed using a user profile that already exists. To manually delete a user profile: From the Control Panel, open Advanced System settings. In the User Profiles section, select Settings. Select the profile that you want to remove from the list of user profiles and click Delete. You might need to restart the machine to see that the profiles have been deleted.
