>We have a class on Dynazip. That has been build a while ago. So, we have Dynazip.vct and Dynazip.vcx. Now, on a server, we have installed the latest version. So, I uploaded my class to that server. When I try to modify the class, it prompts me for the location of the OCX. The class contains an object for the Zip OCX and another object for the Unzip OCX. So, when I do modify class Dynazip, it prompts me to select which object. I then select the Zip object. It prompts me to specify the location of the Dynazip Zip OCX. However, that version doesn't contain OCX anymore. It's just DLL. So, I select the Zip DLL file and it says "Class not registered".

Did you install new version of the control on the server?
