Before I bought Felix I Was testing original RH from web but installed then Felix version to have the settings.
Now I transfomed back to official version by transfering settings!
What I did was:
I made a fresh install of Repetier from their web site (0.95F) and deleted before in regedit
[HKEY_CURRENT_USER\Software\Repetier]
and in file system (HOME=your user name)
C:\Users\HOME\AppData\Local\RepetierHost
I did not run the new installed RH at the moment but did instead:
I copid files from C:\Users\HOME\AppData\Local\RepetierHostFELIXPrinters
to C:\Users\HOME\AppData\Local\RepetierHost
I opened regedit and exported [HKEY_CURRENT_USER\Software\repetierFELIXPrinters] to a reg-file
I edited the file correcting all pathes to the new ones in RepetierHost instead repetierFELIXPrinters.
Also change all occurences of \repetierFELIXPrinters ro \Repetier!
Be carefule, SFACT main directory changes in new version!
There are many lines to change to new path.
Import the changed file with regedit.
Start the new RepetierHost and make sure that potential sfact and Slic3r settings are right, you may need to adjust sceinforce profile location!
Otherwise it should work

You may setup Kisslicer directory as a new slicer to import gcode from there.
Anyhow, I deinstalled Felix version now to have only one RH in system!
Hope this helps you if you want to do the same!
