[WB22] - LoadDLL no longer working [RESOLVED] (2 replies)

This is complex DLL Hell issue - and there is no workaround.

WD19 was able to load a critical "64 bit"dll - [webdev dynamic application running on IIS8.5 on Windows 2012 R2 standard (64 bits)].

Now the same code - same environment - throws an error "..dll is not a valid Win32 application". Note: this is an API interface - I have no access to the DLL code.

I have rolled back recent Windows 2012 patches and tried just about every permutation that I can think of - but it is starting to look like something fundamental has changed in the wd220vm.dll.

Everything works fine on Windows 10 development mode, so it may be related to the way wd220vm.dll code handles the Win 2012 environment (i.e. finding the dll but not the associated .lib file).

At the moment I am pretty much out of ideas, so if anyone has any experience with LoadDLL or can throw-in any suggestions for an approach to track this down it would be greatly appreciated.

I doubt that PC Soft support would be able to help unless I can replicate this with a simple application and some generic dll - but that is a long road.

Anyway - if anyone has any ideas or suggestions ...

Thanks

Derek
