My Computer
C:\Documents and Settings\All Users\Documents is not accessible.
Access is denied.
OK
This error appears when attempting to access the Shared Documents folder (which appears to be renamed to “Documents”)
I recently had this problem on the main computer here at my home. This same problem prevented Adobe Acrobat 6.0 from working, and prevented a reinstall (or uninstall and install), as well.
I’ve finally found a fix. And it’s quite a simple one. Follow these steps.
1. Choose Start > Run, type %allusersprofile% in the Open box, and then click OK.
2. Right-click the Documents folder, and choose Properties.
3. Click the Sharing tab, and then unselect “Share This Folder on network” if it is selected. If it’s not selected, select it.
4. Apply. If you had to unselect the box in step 3, now select it again and Apply.
This causes the name of the folder to change to Shared Folder. This also allows Adobe Acrobat 6.0 to install.
