Thorghem: Thanks it helped :)

planewalker_dk: Here is a way to check which program is causing the game to not work:

"When the game freezes, don't kill the process. Open the task manager and go to the "Details" tab. Scroll down to WHSHR.EXE, right click it and click "Analyze wait chain". A window will pop up with the culprit that's causing the game to stop. I'm on Windows 10, and I don't remember if older task managers have the same option, but this is what I did. "

cheers

planewalker_dk: HOW TO MAKE THE GAME WORK ON WIN10:

Disable any overlays/hooks, as they make the game not work.

Disable any driver optimizations in the driverHQ(nv/ati)

Set language locale to english.
(might need to enable 98 compatability mode too)

QWEEDDYZ: Wing is no more present in current OS. But somehow games from Win9x still worked... i faced that error downlaoded Heroes 2 MnM retail 1.0 base game disc image. There is wing file there in sub-folder, but game ask for it. Copy it to game root folder and game say it should be in Widnwos system folder (there is no such file in any win subfolders for WinVista+).

But that not happened not only for GOG version (i mean Windows build), but also for CD Gold re-edition without dos-version.

So, back to subj... GOG version shouldn't ask for such file and somehow worked. if you use offline GOG version - try to reinstall and make first run as admin later (if game in D:\Games\Warhammer-SotHR\ and not in Program Files or set it lawys to start in admin).
For GOG-Galaxy version - verify game files in games Library. Even if files are correct client will reset\re-register what needed. Better do that twice in a row (cause Galaxy not report what it do).

You can try download that file online (should be digital signature from Microsoft on the file), and put it to game folder and look what it did.
UPD: wait, it should be in game folder, this time for that game. Did it present in game folder for you?
Try to look here

And there is few threads about it. looks like something prevent installer - both for GOG and GOG Galaxy versions - to work properly, and there is many else fiels not been copied.
Turn off AV (unless it if Widnwos Defender, for which one admin run is enough). Redownload installer files. Make sure there is digital signature and it is valid on exe file. Do nit uncheck validate files option duting install configuation.

Move downlaoded files to D:\Downloads\GOG\ and start from there by RMB clicking on exe and chose start as admin. UAC should be at defalut option so you should see admin notice pop-up blocking your Desktop. If that not happened - sometign wrong with your Windows. Turn UAC back to its default.
Install game strictly to D(x*):\Games\Warhammer-SotHR\ .

Eldrak21: Thank you for the response. Unfortunately I am not having success :(
I have reinstalled numerous times, tried running from Admin, choosing different modes to run in but still coming up with the missing WING.DLL

I copied over a WING.DLL file I managed to find but another missing DLL file error was coming up after that which I haven't been able to find.

This is very frustrating not being able to launch this game!
