FSX on new ASUS PC with MS FS 2020

I have my old FSX on thumb drive, from old PC.
I then copied the files to the new ASUS, that has MS FS 2020 installed.
When attempt to start FSX, error message: failure, side-by-side configuration
What is recommended ? I have no DVD drive to reload FSX,
and BTW, 2020 is working.


Highly suggest a FSX forum, as Asobo had nothing to do with it.

Thx WRB, may try that.

You can’t cpy and paste the FSX because on your other PC the FSX is not in your registry. Reinstall it.
