Hi all,Just installed 747-8 expansion running Win7 and am experiencing the problem eith the config file's ability to READ/WRITE. Have read all the docs ( page 7 of pdf ) but it doesn't tell you either where to find the appropriate file or how to manually alter it. Any ideas folks, I'm not that savvy !!Cheers,TAT007

When launching the configuration manager, right mouse click and select run as admin.I wouldn't recommend editing the aircraft configuration file. By the way, full name signatures are required in this forum, you can create a signature block to make it easy.
