"This program is blocked by group policy" Error Appears When Installing Software

Tags windows

This dialog box is in fact a legitimate protection Xavier has implemented against malware installation.

In response to the threat from Cryptolocker and similar malware, Xavier machines have a Software Restriction Policy enforced via Group Policy as of 11/14/2013. This policy prevents applications from unzipping files directly to the AppData folder, a common target.

If a program's installer attempts to extract files to AppData, you will receive the following message:


If you are receiving this error while trying to install a legitimate program, use 7zip to extract the installer's individual files to a folder. Then, run the installer from within this extracted folder:
  1. Right-click on the software installer.
  2. Choose 7-Zip >> Extract to "<folder name goes here>"
  3. Open the extracted folder. There should be an installer (usually a .msi or .exe file) among the files listed.
  4. Run the setup or installer within the extracted folder, and it should complete without errors.
