How to resolve 'Invalid Error Code' at launch

If Alibre Design reports a long error number followed by 'invalid error code' - this is caused by a loss of communications synchronisation between your PC and the licensing server.

This can be resolved by deleting the following folder (where <Windows userid> represents the name of your user account on the computer).

C:\Users\<Windows userid>\AppData\Local\Alibre Design

NOTE: the AppData folder is hidden by default in Windows, you may have to turn on Hidden Items on the View tab of File Explorer.

After deleting the folder contents, re-boot the computer then launch Alibre Design - you should be prompted for registration information (note you will need your activation code).

For those not comfortable deleting system files, the attached bat fill will automatically delete the folder for the current windows user.  Note you will have to give your permission for the file to run - Windows will block it as a security risk unless you explicitly give permission for it to run.
