Captive 7 on Windows 7: Can it run if C drive has been hidden by GPO?

Hi,

None of our endusers has access to C drive. It's hidden by GPO. This seems to cause Captivate 7 to close on startup with the generic error  "application has stopped working". Is there any way to make it work without unhiding C drive? Maybe some folder redirection? I have redirected the folders under Global Settings to a shared folder to no avail. I have given user full NTFS permissions to all C drive and added to local admin, all to no avail as long as C drive remains hidden. Only got it to work if I unhide C drive for the user. Any tips?

OS: Windows 7

Regards,
Zack
