The Virtual Store in Windows Vista and in Windows 7 can cause updating issues and database location issues with TATEMS. You should turn off virtual store in windows to avoid these issues. If your database file (tatems2005be.mdb) was in the windows virtual store then you will need to relocate it back to the "TATEMS 2005" folder in either the C:\Program Files\ or in C:\Program Files (x86)\ folder.
To disable Windows Virtual Store in Windows 7:
Go to the Start menu and in the Search Box type in "Local Security Policy".
Select "Local Security Policy".
Click "Local Policies".
Click "Security Options".
Right click "User Account Control: Virtualize File and registry write failures to per-user locations." and go to Properties.
Click "Disabled" and then OK.
