Why can't instalthe Unal Egine?

I have used the admin mode.
I have tried many versions.
But when I press the Instal button nothing happans. There is no message or anything.
Can anyone tell me what is the problem?

it could be myriad of things and trying to give you a specific answer based on the information given wouldn’t work. give us more information to work from and we might be able to help out. information like system specs, operating system, method of installation trying (from launcher or git), what actually happens when you try to install (something happens even if there is no popup, check cpu usage it may just be slow)

I reseted the PC. It works now.
