The DLLs do not need to be registered at all. Copying them to the app folder is sufficient. BTW, I have a free wrapper class for these DLLs. There is sample code and the class is highly documented with comments throughout the code. Go to the UT Downloads and do a search on my member ID -- 12473.

>I've recently built an .app file for backing up our applications using the Dynazip DLLs. Rather then creating new install sets and registering these DLLs, I want to be able to copy the DLLs into the application folder and have my .app file check to see if they are registered all ready. If they are not registered all ready, I want my .app to register them for use on the form in the .app.
