During installation of the performance or memory profiler, the installation may error with Windows Installer error 1603. Upon examination of the installer logs, you may see the following:

DEBUG: Error 2738: Could not access VBScript runtime for custom action MSI (s) (44:48) [17:47:56:537]: Product: ANTS Performance Profiler 5 -- The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2738. The arguments are: , ,

ANTS Performance and Memory profilers install menu items into the Visual Studio environment using a Visual Basic script. On some systems, this script can fail because VBScript is not correctly installed.

To reinstall the VBScript component, you can open a command prompt and run this command:
regsvr32 VBScript.dll

In some cases, this is not sufficient, as there is a special case in which the VBScript components are registered in a way that does not allow VBScripts to run from inside a Windows Installer package with elevated privileges. To fix this, look for the following registry key and delete it if it exists:

HKEY_CURRENT_USER\SOFTWARE\Classes\CLSID\{ B54F3741-5B07-11CF-A4B0-00AA004A55E8}
