Sorry for this, maybe someone can steer me in the right direction....

A series of unfortunate recent events has caused me to construct a new computer. I have Win 10 Pro. I have attempted to install the sim 4 times from the backups I made when I first bought. As you can see, I get 99.99% of the install, then it hangs up with this window...
So, what am I doing not right? (I have gone over the FAQ but can't figure this one out)

False alarm! I am sorry. I let the last attempt stay on the screen for about an hour and came back and the thing was finally doing the aircraft cloning stage.

The rest of the install went just fine.
