dsAutomation.dll

I have tried to install DraftSight on my old computer running Windows XP Professional (32 bit ) but the procedure has failed due:

There is a problem with this Windows Installer package.A program run as part of the setup did not finish asexpected. Contact your support personnel or packagevendor. Action register _dsAutomationDll, location:C:\\Windows\\System32\\ ...\\dsAutomation.dll"

Can someone hel me?

Thanks Claudio
