26 version installed but won't run

Hi all. asked this question to DraftSight  support last week, still no answer!

Just got a new laptop and installed DraftSight. 

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

Next 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".  It says 'C:\\Users\\andro\\AppData\\Local\\temp\\K2X3E78.tmp\\'

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

Any ideas please?

Other than that, where can I download the 2025 version as that ran perfectly!

Cheers.

Andy.
