This error has occurred when the 7zG.exe file was missing from the program's folder. The error could possibly occur if a different file was missing or in an unexpected path.

How to Avoid

Option 1 - Copy the missing file from another workstation

The 7zG.exe file is typically found in a path such as one of the following:

C:\Program Files (x86)\Bentley\Promise V8i\Promise\Promise\7-Zip
C:\Program Files(x86)\Bentley\Substation V8i\Substation\Promise\7-Zip\

Copy the 7zG.exe file from another workstation and place it into the same path on the workstation with the problem.

Option 2 - Repair the application

  1. Open the Windows' Control Panel > Programs and Features / Uninstall a Program.
  2. Right-click the Promis.e or Substation application in the list of installed programs and select Repair.

If that does not help, uninstall and reinstall Promis.e/Substation.
