Hi again!
Everything works fine now. Some files were missing so I couldn't get it work before.
If you want to install ClearPass on VMware Workstation just import VM to it, adjust CPU number, how much memory you will assign to it and add new harddrive (just like Jibran sead).
Well, You need a licens too but this can be fixed very fast too - contact your local Aruba/HPE partner for more info and help.
Thanks for all help!
P.S: Yes, I know that Aruba/HPE don't support ClearPass on VMware Workstation but for testing purposes this works just fine :-)
