Thank you for any help.

'Run As Administrator...' does the trick
But can anyone explain why does it need Admin privileges? That's unsafe...

Hi ryhoo2,

it's quite simple why MF has to be run n admin mode:

If you have installed MF in Windows protected folders like (C:\windows, c:\program files, c:\program files (x86) or an other folder of the windows protecting system you have to run all these programs in admin mide.
The other way is that you run one of the MF relatd programs in admin mode, you have to run MF in admin mode.

Best is that you did not install the MF related programs on drive C:\. Better is to install it normally on drive D:\,E:\ or any other drive but not on drive C:\
If you install it the normal way (do not activate the admin mode) you can run all mf related programs in normal mode.

Hi StephanHo,

The current MF version installs itself to a C:\User\... folder with no option to choose the installation drive or directory. Any way to change it?

Hi Sergey,

that does not matter. You can install MF in a folder of your choice as follows:

go into the folder where MF has been installed (i.e. C:\USER\...). Click on the file MobiFlightConnector-[Version].zip and copy this file to a folder of your choice (i.e. D:\Flightsim\MobiFlight\
Unpack MobiFlightConnector-[Version}.zip into the folder of your choice. Delete the folder C:\USERS\...\MobiFlight - the folder, where MF has been installed before. Run MFConnector.exe in the folder of your choice and have fun with MF]Version}.zip into the folder of your choice.
Delete the folder C:\USERS\...\MobiFlight - the folder, where MF has been installed before.
Run MFConnector.exe in the folder of your choice and have fun with MF.

Thanks!
