Reset The Registry Permissions Using "SubInACL"

dear frnd

              I think yours zipfldr.dll file is either crpt or its regsvr entry point is missing so no problem reinstall it and try to register .hopoe u will be recovered

The two most common errors when LoadLibrary fails are that the DLL is not contained in the specified path or the path is wrong, or if a dependency of the DLL is not met. There is a tool available on the Microsoft Software Development Kit called Depends.exe that checks the dependencies of a DLL to see if they are met. It then reports anything that's missing or corrupted.

Regsvr32 depends on the Kernel32.dll, User32.dll, and Ole32.dll (along with Msvcrt.dll and Advapi32.dll in Windows NT) to be present to work. Depends.exe also can be used to ensure these dependencies are met. Of course, if you must troubleshoot Regsvr32, it's probably quicker and easier to simply reinstall the original problem program.
