I have carefully followed the instructions in the above links, and this still does not work. I have uninstalled, then reinstalled (as administrator), and still cannot change the Athlete Library location no matter what I do. GoldenCheetah.ini only contains the name of the last opened athlete, not the explicit library location. I don't know if this has any bearing on the issue but when installing, the included VC++Redistributable refuses to install as I already have the 2105-2022 VC++ Redistributable (X64 and X86) on my system. Also, R is not packaged in the installer and is not present on my system. Other than this, GC appears to function correctly in all aspects.
