For those who tried registering Quartz.dll and still face a "class not registered" problem, have you considered that there could be a different class in your system causing the error?
My question to the poster is how did you manage to trace your troubles back to Quartz.dll specifically?
Hopefully that will help me find my own unregistered class. Thank you:)

I came across this when I was trying to find a solution to my problem.
It looks like some of the people responding are merging regsvr32 and quartz.dll and mispelling regsvr32.
There is a space between regsvr32 and quartz.dll. Regsvr32 is an exe that registers dll's.
Hope this helps might not help the people that posted because they might have found other help but maybe the next individual that reads. If not, I tried :)
