OpenCL suddenly is not available anymore (DT 2.7 win64)

Hi, I installed the v2.7.0+ 1859 windows version yesterday and since then opencl isn’t available anymore. It was with the v2.6.
the cltest give the following

any suggestion?

Your opencl compiler is not able to build basic.cl. However it doesn’t tell why.

Open a bug report with precise information. Which graphics card, driver version etc.

On osx i have a similar issue. It needs up to 40 attempts to successfully build all kernels. I created a script to do this annoying stuff for me: current OSX Build
Maybe you can adapt it for windows and it helps there, too

I’ve realized that when I login to my other user profile (on Windows 7) I can select the opencl checkbox. Strange. But also with the newest dt version for windows (2.7.0 +2162) it works on all windows user profiles.
Thanks
