There appears to be a fault with the windows 11 beta extraction tool which is corrputing the extracted files making them impossible to run.
Normally when I extract a zip file I just extract it using the built in Windows extraction tool from the file explorer context menu i.e. right click on the zip file and then choose extract all.
Just recently I tried to install the latest version of FSRealistic and found that the .exe file it extracted would not run at all, no error messages, just nothing happened.
Then again today I decided to install the beta version of LitleNavMap (2.8.2 beta). downloaded the zip file and extracted as above and got the same problem, the files appear to extract OK but the .exe file won’t run.
The solution for me is to use another method to extract the files (I used the free version of 7-Zip). If I extract the zip files using this I can then run the .exe files as normal.
