New Draft sight installation won't start

Hi all.

Just got a new laptop and installed Draftsight. 

It started up and I registered with my personal code OK.

This morning I tried to start it up, and get a message trying to run some code 99f5df6.msi then "the feature you're trying to run is on a network resource that is unavailable"  "Click OK to try again. Or enter an alternative path to a folder containing the the installation package 'DraftSight.msi' in the box below".  the box says C:\\Users\\andro\\AppData\\Local\\temp\\K2X3E78.tmp\\

I've no idea what I'm supposed to do with that?

Any ideas please?

Andy.
