Error in Activex registering

I am using VB6 when I install my application on WIN 95 or NT It gives follwing error
"Activex Component can't create Object".

What is the problem and how to rectify it.when I use ActiveX or other Controls should I register new version

With the existing version of OCX. Will there be any problems later on.

some of your activex control maybe need another supporting activex to be registered.. eg.. some activex that is made using vb5 require vb5 runtime file to execute it... check your activex again if it require any supporting activex.
