Run-time error 429 ActiveX component can't create object

Hi I get the above error every time on startup since installing some software. I have uninstalled the software but still get the error!

I tried system restore but it failed for an unspecified reason, please help!

Run a regular and registry cleanup with CCleaner. Reboot.

In Msconfig, click on startup tab and uncheck any entry that may be related to this problem. Reboot.

Thank you, I was just about to post I found the problem was a file that was refusing to delete fromt he software. I couldn't delete it at first but after shutting down most processes it went to the recycle bin.

Sometimes computing can be so frustrating! *phew*
