draft sight corrupted

Hi,

 

I am running windows 7 64 bit and draft sight seems to be corrupted.

I try to uninstall from control panel and get the following error message.

 

Error 1721. There is a problem with this windows installer package.

A program required for this install to complete could not be run. Contact your support

personnel or package vendor action: Uninstall_swinstactsvc.exe, location: ..\\swinstactsv....

 

is there an uninstaller for draftsight that I can download and run to clean up draftsight and re-install it again?

 

Thank you.

 

Regards
