move done, could not wait any more .. here's conclusion if anyone need to do this themselves
1. make regular backup of your profiles
2. MAKE BACKUPS
3. if you don't have backups, you need to copy from your old registry keys
[HKEY_CURRENT_USER\Software\Simplify3D\S3D-Software\FFF] (and all the subkeys)
DO NOT COPY ALL KEYS!!!! it will not work, it will behave weird, and who knows maybe the activation backend system will decide you are doing something funny and kill your registration so..
there are bunch of keys, I did not touch system keys, only user keys, on the "dead" computer they are in /users/username/NTUSER.DAT file (the registry files are called "hives")
so, if you have access to a ntuser.dat from your dead windows, copy it to your new one in some temp dir, rename if you like to know what's there..
open regedit and load this file in some temporary place (e.g. click on HKEY_USERS and go to file/load hive, select ntuser.dat or how you renamed it to, it will ask you the name of the KEY you want to load it under, give it some value e.g. OLDHCU and voila, you have your hive loaded)
now under the key you loaded this hive in you will find what, for that user, was HKEY_CURRENT_USER and inside you find
Software/Simplify3D/S3D-Software/ - whole bunch of stuff -
what you want is to export FFF (and everything below it) and Gcode
so click on FFF then File/Export and save as some .reg file
click on Gcode and then File/Export and save as some .reg file
unload this hive (click on the temp key you created - OLDHCU or whatever you wrote and go File/Unload Hive)
open the 2 reg files you created with some text editor
you will see that your keys have the "prefix" that's wrong (cause hive was loaded in to other branch of the registry) .. so do a search and replace in the file so that your keys are properly positioned
so to get this:
you do a search/replace of "[HKEY_USERS\OLDHCU\Software" to "[HKEY_CURRENT_USER\Software"
same thing for both files
now save & close, double click on files to load this setting into your registry (one by one) and voila when you start s3d it will have your profiles and settings saved.
you will notice huge blobs inside the registry, this is because it looks like S3D stores the object data (last loaded etc..) in the registry itself ..
