MobiFlight Community Support

Tried to install Mobiflight but I am getting an error, "Requested registry access is not allowed.", and the program will not start. Tried different directories and run as Admin.
Would greatly appreciate any help.

Ifficial Download link from this Homepage ?

I never heard about that.
Please confirm you download the installer file and you just run it.
Does it "unpack" the whole MF Files and the isue is occure when you try to start MF .... OR does already the installer will not work ?

Thanks for responding. Downloaded installer and double clicked . It unpacked about 25 files and the start screen appeared and error warning popped up.

"Application attempted to perform an operation not allowed by security policy.To grant this application the required
permission please contact your system administrator or use MS.Net Framework Configuration tool."

if I click continue the error message closes but the MF start screen does nothing. HELP!

Please check your Windows status. ( By the way. Do we talk about WIN10 ? )

The error text tak about Net.Frame. This is sometimes a bit problematic.
Mobiflight is based to newest Windows releases and get patched if here something wrong is reported by the users.

So.... Please make all available Updates for Windows.... Specialy all Net.Framework patches !

Thank you, I am updating every thing now.

the updates fix the problem, thanks so much for the help.
