Error code is 2502 or 2503

Installation troubleshooting

While installation, you may get a 2502 or 2503 error:
Error 2503.

The problem may be that access to the C:\Windows\Temp folder is restricted. To solve this, unzip the folder with the add-in files, right-click the setup.exe file and pick the Run As Administrator option:

Run as administrator.

And follow the Setup Wizard instructions. If this doesn't help and you get the same error again, please contact us at
