Getting tenno-gen with non-steam version?

[DrProfSirCarmen]

Is it at all possible to make my non-steam version able to have tennogen, whether it be something simple like just adding it to steam or something weirder? I'd really rather not re-install the game on steam, especially with how it basically takes double the time.

You can supposedly move the normal one over to steam and change some registry settings. 

I haven't tried this because I was doing a reinstall at the time so did a different approach to my usual install the standalone, I went the install via steam, then change settings so it runs without steam needing to be active but it still allows me to login via steam if I want to say for tennogen (which should work in standalone but never tried it due to high cost of tenongen items)
