My 2 cents for my first post: [HKEY_USERS\S-1-5-18\Software\GlobalSCAPE\CuteFTP Professional\Index] "3"=hex:73,6f,2c,20,77,68,*** "1"=hex:41,35,55,52,47,54,*** Thoses two keys seems to depend on the Key : didn't work for me until I put the key generated by a clean install using my key. The online check seems not to like those too much in my case. I only install the Pro version and only got the second "1" key btw. Anyway, first time I launch CuteFTP, it pops up with the Enter your Serial windows (I double check my key and all). Second try : I change the reg file to reflect the "1" key genrated by a non-silent install : works like a charm. Am I writing some idiotic stuff ? May be you want to hide those in your post ? And apologize if I am wrong.
