I am trying to run Mathcad on my new machine (Windows 7 – based). However, I always get this message denying me accessing the software: "You must unload your debugger before you can run this program".
If you have additional components installed that are related to Mathcad, you need to uninstall them and then perform a new installation. If you still encounter errors, use Revo Uninstaller to force an uninstall procedure then use CCleaner to clean the registry files and in the last step install MathCad. Make sure to apply a compatibility setting. Right click the install package and select Troubleshoot Compatibility and follow the instructions.
