Error 1327 - Invalid Drive: P

This information is intended for system administrators.

Issue

When installing Jet Reports on Windows Vista, Windows 7, or Windows Server 2008 and higher, you may experience the following error:

Error 1327. Invalid Drive:  P:

where "P" is a mapped network drive. This is because the installer is running with elevated privileges as an administrative user which does not necessarily have the mapped network drive.

Resolution

Follow these steps:

1. Disconnect the previously mapped network drive from Windows Explorer by right-clicking the mapped drive and selecting the "Disconnect" menu option.

2. Right click Command Prompt in the Start Menu and select Run As Administrator.

3. Type "Net Use p : <folder to map> ".  Where "p" is the drive letter you wish to map.  (This will add the mapped drive for the Administrator.)

4. Close the command prompt.

5. Open Windows Explorer.

6. Right-click "Computer" and choose the 'Map network drive' menu item.

7. Select the same drive letter as before and type <folder to map> into the "Folder" box and click "Finish". (This will re-add the mapped drive for the current user.)
