As part of the program, we have to require Powershell to be installed. I can call other programs outside of the virtualized application with no problem and the powershell call works fine inside of Windows XP Pro tests - again with no problems. But when I call this powershell installer outside of virtualized application on a Vista Business or Windows Server 2008 system, it throws a "Windows Update Standalone Installer" title message box with the following error message: "Installer encountered an error: 0x800401f0. CoInitialize has not been called."
But when I just go to the folder and run the Powershell installer directly inside of Vista/Windows2008, I get this error. Again, this works fine inside XP Pro or separately outside the virtualized ThinApp.
Any ideas?
