Adobe brings HRESULT Class not registered

Good day!

I'm using standard pdf from adobe control that perfectly loads PDF on my PC, but on any other it returs and error: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)) It happens only if there is a pdf adobe on form, and only on other computers. I tried to change platform to x86 but didn't work too ;/ Any ideas?
