Hi,
Please try the two methods and check if they are helpful:
One:
First, log on as a new Windows user to the computer to see if you have the same problem. If you can open Property Sheets as the new user, export the following registry key in regedit:
HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Access\Settings\CommandBars
Then, log on as the original user, and double click the exported REG file to import it.
Please note: Backed up the registry before modify.
Two:
Press CTRL G to get an immediate window
- Enter this: 'CommandBars("Property Sheet").Enabled = True' and hit Enter (drop the single quote)
