PFPX and CTD unter W10 v1709 in PFPX - Professional Flight Planner X Posted January 9 1 hour ago, srcooke said: You may also wish to try the 2017 vcredist that works here without issue also. Thanks for the hint Stephen, I'll try this first before changing the 2015 packages. EDIT: The 64bit version did nothing, but the 2017 x86-package made it. 1 hour ago, srcooke said: Did you actually try the version Tom linked to ? Not all 2015 SP3 vcredist were equal, at least one version from Microsoft would cause errors. If nothing works I'll swap the existent ones against those Tom linked to. EDIT: No more necessary. Thumbs up Stephen!!! Now I can uninstall PFPX again in order to place it where I want it to be.
