Hi folks, I just updated from 12.1.7.0 to 15.0.4 using the EXE, and all my settings were wiped. I don't even know where to start in order to get back to where I was. I will say that some files, such as the log, still seem to be the old version. So I re-ran the installer for 12.1.6 (seems I didn't download the 12.1.7 EXE)... Hold up...
The installer is removing spaces from the user data path. The installation created a second data folder. The proper spaces are shown during setup, but it creates the new folders and sets up the erroneous data location.
Sorry if this was already figured out and I missed the post.
Working around...
