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.
Follow these steps:
Disconnect the previously mapped network drive from Windows Explorer by right-clicking the mapped drive and selecting the "Disconnect" menu option.
Right click on Command Prompt in the Start Menu and select Run As Administrator.
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.)
Close the command prompt.
Open Windows Explorer.
Right-click "Computer" and choose the 'Map network drive' menu item.
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.)
