Win 10 64b, Ryzen gen 2 2700X, gtx 1660 Ti.
I fetched, installed and tested.
Runs just fine here.
Have fun!

I also have a Ryzen 5 at it works for me
Ok, the problems seems about compiler flags.
I found an option in the CMakeLists.txt to disable the compile optimizations for redistributable package build.
Here is DT 2.6.2 built with that option enabled.
Please test it on Intel CPUs. If it works, I will make DT 2.7 as well.
Same result for me Iâm afraid. 
AMD FX 8350 âŚWin10 ProâŚThis build for me doesnât appear to runâŚdoes nothing opens and closesâŚopencl test generates an unhandled exceptionâŚso still no joy âŚyour a trooper for tryingâŚI am assuming the builds work for you??
Not sure which option you found but this one looks promising:
option(BINARY_PACKAGE_BUILD "Sets march optimization to generic" OFF)
Of course, anyone who actually knows what theyâre talking about, feel free to correct me⌠lol
Are you on win10 Pro or home??
Seems to work on Ryzen from a couple of replies so you could be on to something also wondering about the Win versionâŚI saw a Home user say it worked for him and your 2.7 version worked for me on a PC using Win10 Home but the two PCâs I tried earlier with Intel i7 and AMD 8350FX respectively would not run so I wonder if it is something related to thatâŚif anyone gets it going on Pro then that shoots that theory downâŚ
ClaesâŚis that WIn10 Pro or Home version??
I have Windows 10 Home, Version1809, OS Build 17763.437 with nVidia 750.

Thanks for sharingâŚI have not seen one person that said they were running on Pro that got it to work so maybe there is some issueâŚI will dig into what that could beâŚ
Yeah, this is the switch I activated, but apparently doesnât solve the problem.
Iâm running out of optionsâŚ
If the official DT 2.6.2 works for you, what I can try to do is to contact the maintainer of the Windows build and ask for help
Yeah, the official 2.6.2 works for me.
Just a thoughtâŚ
After setting the before mentioned option to on, did you delete the previous build before starting the build again?
This maybe a silly question but you never know.
Hey thanks for spending time on thisâŚit would be interesting to know what the issue is but the stable release works for me so I just need to find time to try and compile on my machine or wait for the official release of the new featuresâŚthanks againâŚI did some googling to try and see if there was something intrinsic to the Professional version that might explain the issue but I didnât uncover anythingâŚ
Win 10 Pro
I was able to reproduce the issue on my company laptop with Intel i5 running Win 10 Pro.
I could try to set up the build environment there and check if I manage to get a package that runs on both platforms.
@Marctwo
Yes, I did a clean build, but no luck.
Looking in âcmake\march-mtune.cmakeâ with âBINARY_PACKAGE_BUILDâ set you should get the message â-- Checking for -mtune=generic supportâ. Do you see that message when building?
Yes, thatâs what I get.
Here is the complete output
$ cmake -G "MSYS Makefiles" -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/opt/darktable ../.
CMake Deprecation Warning at CMakeLists.txt:5 (cmake_policy):
The OLD behavior for policy CMP0048 will be removed from a future version
of CMake.
The cmake-policies(7) manual explains that the OLD behaviors of all
policies are deprecated and that a policy should be set to OLD only under
specific short-term circumstances. Projects should be ported to the NEW
behavior and not rely on setting a policy to OLD.

That looks like itâs only the build configuration output.
Iâve never used this build environment but Iâd expect to see a lot of output from the compiler tools.
The two 2.6.2 installers youâve linked are:
1. darktable-2.6.2+4~ged2c42df9-win64.exe
2. darktable-2.6.2+4~ged2c42df9-dirty-win64.exe
Both versions when installed have exactly the same folder size (301,184,462 bytes). This with the âdirtyâ in the second filename seems to imply that the second version wasnât a clean build.
Again, I donât know this environment but are you sure you deleted the build folder between builds?
