When I right-clicked on it I get the following message: Otherwise click Cancel to abort the installation.Īfter I managed to finish the installation, I noticed the icon of the program with an exclamation mark in System Tray. Please make sure that Sandboxie Control is not running, and that no programs are running sandboxed. When I try to install the program (overwrite the existing installation), the setup is stuck to this step Extract: LICENSE.TXT.Ĭannot create or update Sandboxie program files. I tested the new versions (5.55.4-5.55.6) on another machine (Windows 10 Enterprise LTSC version 1809 64-bit) and they are working as usual.

The last working version of Sandboxie Classic is 5.55.3. I did not changed the Sandboxie.ini configuration file. I have no security software running in the background, except Windows Defender Engine Version: 0.4.

I have Windows 10 Enterprise 2015 LTSB 64-bit. Starting with 5.55.4, the program no longer works on my machine.

I updated the program (Sandboxie Classic), version after version, since the new development.
