Unable to deinstall / remove and install draftsight

Dear all, 

I hope someone can help. 

I cannot remove draftsight (Throug configuration/software/add remove programs) When i try to deinstall I get the following message:

When I try to reinstall Draftsight I get basically the same error. 

 

I have searched here for a solution however I have not been able to find it.

Oh and My computer runs on Windows 10. 

Best regards,

Marco
