I was making project in vs 2012 so by default its framework was 4.5 i mange to copy .pdf file path to my datebase etc every thing was working as planned
but when
i changed the framework to 4.0 then adobe reader was giving error even if i put it on a form without binding etc.
the error is "Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"
i even change framework to 4.5 but again its giving the same error
what should i do it urgent
