This is the updated uncracked Steam release of the Photonflowers beta given to backers, this is assumed to be the Steam launch version given that it was recently updated to include a bunch of typo and grammar fixes. Included below is a message left by poster Infernoplex on the original photonflower beta release who states how to get the game to run. Infernoplex - "First, make a copy of the Photonflowers folder you got from this torrent. Or put the game somewhere else if you are not actively seeding. Then grab this: https://drive.google.com/file/d/1FUsPWdPVXiRlLwaP9ZWHmv5MBQAZJmnS/view Extract everything into the Muv Luv Photonflowers folder, the copied one or where you moved the game. Go to the game folder and run “muv-luv_photonflowers.bat”. This will copy all the registries needed for Photonflowers to work into your registry. And then just run the game using “SmartSteamLoader.exe”. That’s basically it. When you finish with the game, or want to uninstall, just remember to run “muv-luv_photonflowers_unreg.bat” to get rid of the registries you had to install because of the VN. The Age’s engine is a pain in the ass to make it work because it doesn’t automatically create them when you want to run the game. I guess if you are installing through Steam, it gets installed normally, but if you are pirating it, you must do it manually. I had the same problem with Muv-Luv Alternative and had to do the same thing for this one. Notes: The registries installer I shared here is based on the old registries installer for Muv Luv Alternative that were made by PrinterDesu. I couldn’t bother myself enough to write my own, so I just modified his to make it work on Photonflowers." - quoted from https://sukebei.nyaa.si/view/2674106#com-3
