Zlib decompression is not working on 64 bit configuration

Jithin Jose

I am using Zlib1.dll ver 1.2.3.0 for compression and decompression of an image. Everything is working fine with 32-bit build configuration. But when I try to compress the data with 32-bit and decompress it with 64-bit on the other side I always getting the Z_DATA_ERROR(-3). But by using .NET framework above 3.5 (eg 4 or 4.5) the 64-bit decompression working fine.

you have to dig into further to findout that on the machine where error occurs

check the system event log if you can find any details or look on the third party documentation for this error.

But why it is working above .NET framework 3.5?

I think its the way the third party dll is created, and there is nothing you can do to fix it

you can contact the product support and they may be able to help
