Hi Friends,
I have created my Desktop app using VB 6 - ACCESS 2K.
I have used msado 2.6 reference connection object, and Microsoft OLEDB 4.0 Provider to open secured database.
In Deployment , i have used registered msado15.dll , MDAC 2.7 and Microsoft oledb4.0 SP.
I also deployed DCOM95 , DCOM 98 in my setup.
After installing , when program runs, it flags error " Activex Component can't create object " in some WIN 98 OS and on other it works fine !!!!!!
what is reason behind it ?
what steps i need to solve it ????????
