Sakura installation help!

Okay so i bought sakura from plugin boutique, downloaded it & installed. I even registered the serial number and unlocked all my products but didn't work. In FL studio 20 it still showed the trial version. I looked it up on youtube and messed with the folder, replacing the old stock files with the one i downloaded in program files 86- image line -fl studio 20- plugins - fruity & vst. Now when i try to open sakura in fl, it says it cannot be found! Please help i love this plugin & have registration. Thank you
