We have a client who has an old in-house app that relies on the DynaZIP 32-Bit OCX Interface to run. Â We’ve been trying to get it to run under Windows 7, but couldn’t find much info — but I happened to come across a text file from DynaZIP that had the dependencies on it, and it turned out we were missing a couple files; loaded them into SYSWOW64 and the OCXs register.
You need to make sure the following files are in your c:\windows\ syswow64 directory:
- OC30.DLL
- MSVCRT20.DLL
- MFCANS32.DLL
- OLE2.DLL
- COMPOBJ.DLL
- STORAGE.DLL
- OLE2DISP.DLL
- OLE2NLS.DLL
- TYPELIB.DLL
- DZIP32.DLL
- DUNZIP32.DLL
- DZOCX32.OCX
- DUZOCX32.OCX
- DZSTAT32.OCX
Then open a command prompt with admin privileges and run REGSVR32 on the lot of OCXs.
