I'm trying to install Quickbooks 2004. The disk auto-runs, and I choose the installation option. The following message appears: The operating system denied access to the specific file. qbooks\setup.exe How do i get around it? I tried manually running the setup but the program would not respond. Unlocker did nothing. I'm installing this for a friend, and she needs to get QuickBooks on her laptop so that she can take it to her accountant, and she needs to be there in a few days, so any help would be appreciated.
