[@beergas] SOS vovsoft giveaway come pre-licensed in the coding of the program, they are special builds that do not rely upon the registry for license storage and do not need the vovsoft license activation server accepting the license key for re-activation in the case of giveaways. SO you should not have any problems with SOS Vovsoft giveaways.
Does it show as Trial Mode in the bottom left corner? Mone does and Im on Windows 11 Pro too.
