Happy to help
For those of you who didn’t have the dubious pleasure of growing up with the intricacies of MS-DOS:
Just create a common text file on your desktop. Name it something like “Start MSFS.bat”
Mine looks like this. You have to insert your correct folder names of course. And if you have a path with spaces in it (like below with FSRealistic) your have to put that in quotations. The last line then starts MSFS without the splash screen videos. This should work no matter where your MSFS is installed. There is a possibility this path only works with the Microsoft Store version. Can’t test it with Steam.
start “” D:\MSFS_Tools\AIFlow\AIFlow.exe
start “” D:\MSFS_Tools\AIGround\AIGround.exe
start “” D:\MSFS_Tools\FS-ATC-Chatter\FS-ATC-Chatter.exe
start “” “C:\Program Files (x86)\FSRealistic\FSRealistic.exe”
start “” C:\Windows\System32\cmd.exe /C start shell:AppsFolder\Microsoft.FlightSimulator_8wekyb3d8bbwe!App “-FastLaunch”
