That error is:

Setting a property using setzipvalue or setzipstring function failed.

which is a zip function. Can you post your unzip code? You can also use my free DynaZip class that is a wrapper for the DynaZip DLLs.

>I have taken over an application that uses DynaZip to unzip files. I can successfully unzip the file using tools like WinZip but it fails to work with DynaZip which returns an error code 49.
>
>While it is nice to capture that an error occurred, it would be even better if the file unzipped successfully. Anyone know how to get around this error code short of abandoning the use DynaZip?
