Wow! Thanks Robin, for the detailed "how-to" tips. Similar issues with my Win10 setup. Just in case installing to C:\ doesn't always work, I've had some success installing FS9 (and other older sims & games) into C:\Games\. Win10 doesn't seem to cause so many issues when installed there. Another alternative, which has worked best for me, is to re-use my old WinXP hard drive from my old PC and set up a dual boot for running older sims. Thanks again for your detailed "how-to". :)
