I've been installing XP applications in XP Mode for a while with no issues. Today I tried to install TextBridge Pro 11 and received the following message:
"This installation could not be opened. Contact the application vendor to verify that this is a valid windows installer package."
I varified that the software would install on a PC with XP as it's main operating system.
I searched the internet for issues that seemed similar. I updated Windows installer to 4.5, I reset the installer service to automatic from manual, temporaily disabled antivirus and the firewall, and restarted and rebooted several times with the same result.
Again this is the first application I tried to install that has given me any issues.
Because the application installed in a normal XP environment, I tend to think it has something to do with virtualization. Has anyone encountered similar issues? Any help would be appreciated.
