A little heads up should this happen to you.

 

W7 64bit. Updated NVidea drivers 732.54. No problems. When to start FSX and (a) noticed the shortcut icon had reverted to that system thing. Instead of FSX starting I got an error message along the lines of "This program wont start because it's incompatible with your system blah blah 32bit blah blah 64bit refer to the program developers"

 

Lapse into OMG! mode.

Googled like a man possessed...Nothing.

Went to FSX root folder and clicked on fsx.exe. Same message.

Many emotions ensued including 'Oh well, I've got P3D' and 'Bugger, I'll have to re-install everything'

 

Calmed down enough to start digging in the fsx.exe's properties. Previous Versions gave me an option of restoring a previous fsx.exe. I clicked, a box came up asking me if i really wanted to restore something so very old? Why not? So I said 'Go for it'

 

Long story short, it did the trick.

 

Got the old ticker pumping, that's for sure!

 

 

I take it you mean driver version  372.54 released 15  08  2016.

 

Thanks for the H U Ron.  Will give it a miss & stick with what I have,  368.22
