If you do not have all the necessary files, you can download them from this web page. Please check carefully that you have provided the full drive and path information for those items that require it. Any deviation from this pattern will not work. If your program has a large number of files open at one time, you can reach the DLL's internal limit of 50 files open, and DynaZIP will no longer be able to create an output file. If this occurs, close some files, or spawn another task that will call DynaZIP for you.
Strange errors happen, like dialog boxes coming up partly drawn, etc.
One possible reason is insufficient stack space. Please check your compiler or development language manual and increase the stack size. 15k is minimally acceptable, 20k is better. This works fine under Windows 3.1 but returns an error when I run it in the Windows 95 or Windows NT environments. How do I use the Setup Wizard that comes with Visual Basic to automatically include the DynaZIP OCX controls and any dependent files they need.
