RESOLUTION
To resolve this issue, use the program that you used to modify the location of the Program Files folder to restore the default location of the Program Files folder. If this does not resolve the issue, verify that the ProgramFilesDir and ProgramFilesPath registry values point to the correct location of the Program Files folder. By default, the Program Files, or %programfiles%, folder is located on the same partition as the Windows, or %systemroot%, folder.

Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.To restore the default location of the Program Files folder, follow these steps: <ol> Click Start, click Run, type regedit in the Open box, and then click OK.</li> Locate, and then click the following subkey in the registry: </li> Back up the registry key: <ol style="list-style-type: lower-alpha;"> On the Registry Editor File menu, click Export.</li> In the File name box, type a name for the backup, and then click Save.</li></ol> </li> In the right pane of Registry Editor, double-click ProgramFilesDir.</li> If the correct path of the Program Files folder is not displayed in the Value data box, type the correct path of the Program Files folder. For example, type C:\Program Files .</li> Click OK.</li> Double-click ProgramFilesPath.</li> If %ProgramFiles% is not displayed in the Value data box, type %ProgramFiles% .</li> Click OK.</li> Quit Registry Editor.</li></ol>
