Having issues with Citrix on a Windows 7 Pro (64bit) machine. Now I can't even uninstall the Citrix online plug-in, gets near the end of the uninstall and I get "There is a problem with this Windows Installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."
I was able to determine is it Citrix error 1603 'XenApp Web Plugin'
