Hi subSTRATA, thanks for reporting the issue. I added a "Set Bitcoin data directory" option to the solo utilities, and as well it accepts any .EXE file for the bitcoin executable. To use it, set the bitcoin executable and data directory correctly before launching the bitcoin-qt.exe.

Your bitcoin.conf needs to be set up properly in the other data directory as well, the "create solo password" option only knows how to write to the default data directory.

Let me know if you experience any problems, but it seemed to work on my machine.
