A mirror for the Unofficial Arcanum Patch (UAP) is:
Installing [Arcanum High Resolution Patch] [1.5]

Checking version...
Copying and patching 1 file ...
Arcanum.exe version (English) required.
Stopping installation because of error.
Which is weird since Arcanum.exe properties says "version (English)"
Any ideas?
I have the exact same problem as badunius. Tried to patch manually to with the appropriate Patch-file. But that only broke the game entirely. :/

So I've got it to work now. Playing in german language in 1920 x 1080 resolution with no stuttering so far.
My steps:
1. Made a clean install with GOG-Galaxy
2. Installed the german patch from Compi-Ware
3. Installed the two inofficial Patches UAPv081004 from Drog Black Tooth’s (posted in the "Sammelthread zu Deutsch-Mods..." from user PoooMukkel
4. Installed the HighRes 1.5 patch with DDrawWrapper = 1 - which suddenly worked after installing the two inofficial patches

Maybe this helps someone. :)
And sorry for my bad english

@badunius: I think the HighRes-patch will work after installing the unofficial patch.

I recently got Arcanum, downloaded it and the various patches described (and linked) on this thread, I had no problem running the game under Windows 10, 1920x1080p resolution.

Thanks to everyone for making all the information and files available!
If you download the unofficial patch and apply it then the high res patch will install.

The GOG version comes pre patched with some old version of an unofficial patch I think. It'd be better if they just supplied the original exe.

mirror with hq music and town maps. The music is worth the better quality recording.

also now ddraw compat wrapper doesn't seem to work, the version supplied with the high res patch or the latest one. dgvoodoo seemed to be freezing up sometimes, gl
