[Resolved]Error with FSLOptions.dll


Recommended Posts


I purchased the FSLabs A320 and after installation I am getting an error when I try to run FSX about the FSLOptions (see attached image). If I press YES, FSX exits, if I press NO cannot load A320 and FSX crashes. I am running Windows 10 & FSX Acceleration

Please assist.

Thank you,

Q: I am getting the "Flight Simulator has detected a problem with a third-party software program (add-on): Name FSLSounds.dll (or FSLOptions.dll or FSLSpotlights.dll): Do you want to run this software (not recommended)? Then, even if I click Yes, Flight Simulator crashes.

A: This is because something caused an error in a previous load of Flight Simulator and Windows decided to intervene and permanently mark that DLL as unsafe. You need to run "regedit", find the registry setting for

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

and in there, edit the entry for fsx.exe to REMOVE any mentions of

Data = $IgnoreFreeLibrary<FSLSounds.dll>

(or the other FSL dlls accordingly).

Then, restart FSX - you'll get the error message once again, but click Yes, and the application will work correctly this time.

Also, make sure your FSX is running as Administrator.
