Dependancies Is Missing Its Called FUSIONButtons.ocx

I have something really strange happening here i have this prog and it says a file or one of its dependancies is missing its called FUSIONButtons.ocx so i looked around and several sites have it but every time i try to download it i get an error. ive tried several sites and some of them were rar files and when i extract it nothing shows. so a friend of mine has the same software with the same problem and got the ocx file no problem and tried to send it to me over msn every time there was an error most of the errors were cannot read source file or filer no longer exists the rars gave no error and was inside when i looked but if i extract here nothing appears. I have 2 computers one with XP sp2 and another with vista ultimate x64 and ive tried a bunch of sites and several friends who have the file on both computers and its always the same thing. The last thing we tried was to rar the whole prog with the need file included and when i got it that 1 file had disappeared or would not show on my systems. I turned off all my firewalls and antivirus, i must add that the first time i tried to get it nod removed the file so i shut nod off and i also went in and set folder options to show all hidden files. I also tried putting the whole rared prog on a flash drive and extracted it on the flash then tried to run the prog from the flash but same thing. Can someone pls explain this wierd thing thats going on here its driving me insane !! i must also add that this is not happening with any other files now or any other file i can rememeber
