I "Replace DLLs manually". Yes, in 4 different system folders I replaced dlls manually but I got StackHash_c6d7 error this time, as I said before. Then I changed back to original dlls manually in all 4 system folder locations manually.
Now I am getting previous error message ig7icd64.dll
Tomorrow I will create crashdump.
Oh, my laptop Microsoft Surface Pro 3, and it says that I am using latest version of graphics driver, and does not let me install any other (or newer) graphics driver.
Meanwhile I downladed 32 bit exe and tried it but it gave ig7icd32.dll error.
