How do I perform a 'complete' uninstall of DesignSpark Mechanical (DSM)?

A 'complete' uninstall means removing all DesignSpark Mechanical activation data from your computer.

This may be helpful if you are facing a serious issue with operating the software or due to a recent hardware change.

The steps are:

1. Go to 'Programs and features' on your computer and then manually uninstall DSM from there.
2. Next, search for 'regedit' to open the Windows registry. From here, navigate to the directory HKEY_CURRENT_USER\SOFTWARE\ and delete the 'SpaceClaim' entry.

Alternatively, run this from the Windows command terminal (open it as admin):

reg delete "HKCU\SOFTWARE\SpaceClaim" /f

    3.   Delete this folder: C:\Users\"Your Windows Username"\AppData\Local\SpaceClaim

Version 4.0 and newer:

You will need to uninstall both these items from the Control Panel-> Programs and features area.

PAID ADD-ON MODULE USERS only:

If you have bought multiple licences and want to replace a licence key on the same computer, please run this file after completing the above:

C:\Program Files\DesignSpark\DesignSpark Mechanical 5.0\ResetLicense.exe

Errors while uninstalling:

1. Running this Microsoft trouble-shooter to fix most uninstall error codes: https://support.microsoft.com/en-us/topic/fix-problems-that-block-programs-from-being-installed-or-removed-cca7d1b6-65a9-3d98-426b-e9f927e1eb4d 

2. If #1 does not resolve the issue you may have a damaged installation of DSM; use the CCleaner application to fully remove the program and re-install using the latest version on the DesignSpark website.
