Unable to install Parallels Tools. Error 1304

  • Parallels Desktop 10 for Mac Home Edition
  • Parallels Desktop 9 for Mac Standard Edition


I am unable to install Parallels Tools. The following errors appeared in parallels-tools-setup.log:

   [G] MSI (s) (BC:AC) [12:33:06:465]: Prodotto: Parallels Tools -- Errore 1304. Errore durante la scrittura nel file C:\Program Files (x86)\Parallels\Parallels Tools\Drivers\prl_fs\ Assicurarsi di disporre dei diritti di accesso alla directory.
   [G] MSI (s) (BC:AC) [12:33:06:465]: Transforming table Error.


NOTE: This issue also might occurs on a real PC's

The 1304 & 1305 errors on Windows are shown when you try and install software, and specifically the Microsoft Office application onto your Windows. The reason for the 1304 & 1305 errors to show are largely down to the likes of software issues, hardware problems and other Windows errors.

Parallels Desktop update provoked the existing issue to be showed as after the each update Parallels Tools installation takes place. Parallels Tools is a powerful package of drivers for the Windows-Mac integration. However, Parallels Tools installation does not take any effect on the system itself. If something was wrong previously you just can never know about that before the installation of any powerful applications / drivers.


In order to fix the issue please try to repair your system as described in this article.
