Hope this is usefull to some of you. Worked for me but try at your own risk.
My win10 installation crashed irrevocably after an automatic update (..grrr Microsoft) and along with every other program and settings (data was on separate drive) I lost my painfully configured FFF settings for my three custom built printers. No backup of those....
So this is what I did.
Installed a brand new ssd for the freshly installed Win10. Left the old disk untouched with the bricked system on it for the moment.
(thanks to NEUTRON16 whose istructions I followed :https://www.sevenforums.com/general-dis ... stall.html
(But as long as you still have access to the old drive or a Registry backup either of those would work)
Since Simplify stores it's settings in the registry I thought it could work for me as well:
Press Start obr - type REGEDIT, open it.
Open HKEY_LOCAL_MACHINE, then File - Load HIVE.
Browse your old hard drive DISK:\Users\%USERNAME%\, highlight file
NTUSER.DAT and open it.
That is HKEY_CURRENT_USER of your old Windows.
It will ask you for a Key Name, enter 123test
Now you will see that HKEY_LOCAL_MACHINE has got a new thread - 123test.
That is actually old registry mounted.
Go to 123test\Software\simplify3d, right click Export. (give it a name and save to any location)
Then click head thread 123test, and File - Unload Hive.
Open exported reg file in NOTEPAD. Edit - Replace, replace all
save that reg file and run it.
This process reloaded all my FFF profiles!!! and all seems to work fine.
