Forum > Zlib not found error in IntraWeb Version: 11.0.65

Hi All,

I have an old Intraweb project from 2019.

The original project was build in Delphi 7 on WindowsXP (x86) , VCL for the Web Version: 11.0.52. (Build Date: Sep 09, 2011) Edition: Ultimate

I used zlib.dll version 1.1.4

I have recently move computer from WindowsXP to Windows 10.

When I compile this project on a new PC Windows 10 (64bit) , Delphi 7 using IntraWeb Version: 11.0.65. Edition: Ultimate

I copied the same zlib.dll version 1.1.4 in my application folder as before.

When I set Compression Enabled and compile I get the following Error.

Exception EReadError : Error reading IWServerController.Compression.Enabled : zlib.dll not found in C:\Temp

In fact even on a fresh Hello World test project I still get this error.

I think it could be due to wrong zlib.dll file. I have tried to download multiple version of zlib.dll (including the latest 1.2.3) but still get the same error.

Can anyone help?

Current Environment

Delphi 7

OS : Windows 10 64bit

Edition: Ultimate

IntraWeb Version: 11.0.65

Build Date: Aug 17, 2016

Regards

Andy

IW 11.0.65 requires ZLib version 1.2.5. Be sure you have this version installed.

Thanks Jackson..

I also need to rename the file to zlib1.dll instead of zlib.dll

Issue Resolved....
