There are Three (3) registry keys, that control the various Paths to the iStripper files.
actually 4 if you are using multiple locations for your Models.
ModelsPath - controls the Single Location of where your Models folders are located
DataPath - controls where your Data folders are located.
and
ModelsMultiPath - contains ALL of the different Locations when you spread your Models folders to different locations

The Installer will use all of the above Locations from the Registry.



The Last one is
MainPath - This is a special one that controls where the Binary File is located and the Start Path for all of the Dlls and Support files.

The Installer does NOT use this registry path, During the Update or Install process.
The installer uses your Systems User profile and it will then set the MainPath to Match where it installed the Binary files to.

There is no way to get around this.

I too use a custom location, so when I install or Update here is what I have to do:
3 steps
After the software has completed its install or Update,
1- I have to Quit iStripper.
2- Copy the BIN folder from my Systems User Profile Path
to where my Custom Location is.
3- I have to Edit the MainPath of the Registry to Match where my custom location is.
