I currently have several copies of Attachmate 6.3 that I am trying to run in Windows 2000 Pro. This will only work if the user is set as an Admin or Power User for the local machine. If they are not, then an error of: Cannot find the security file, occurs. I found this thread mentioning this issue with Extra 6.4 with Windows 200 Pro ( see link for thread at bottom). None of the fixes I tried there seem to have worked. I was wondering if anyone has come across a fix that is known to work or has any new information on this topic. Thanks for any information that you can provide.
