DaVinci Resolve 15 wont open in W7

After I installed Davinci resolve 15, it opened the screen and then it asked for openCL configuration. The error message was " Resolve cant find openCL capable GPUs" . I made changes in the resolve configuration and updated my device driver. Then tried to reopen resolve, Now it wont open at all. Please help me on this. Thanks in advance!

Zimi, not necessarily related to your current issue, Resolve 15 is expecting w10 as a min OS.

Whooo, it's the explantaion why you don't post my question Peter (Resolve don't run with error api-ms-win-core-synch-l1-2-0.dll win 7), me to i'm on Seven, it's sad news for me, Resolve 15 seems fantastic.

I'm disappointed.
