Fail to open/uninstall/install

I was using my software just fine until I try to install another app (Vray for Rhino), then part of the Adobe software seems to crash. Icons couldn't display properly.

When I tried to open any of them

when uninstalling system says an exe file can not be found

When I try to skip unstalling and directly install the app, it says another file is missing

Adobe Acrobat seems different but for similar reasons....

Creative cloud seems to be working, but its not responding when hitting install or unintall or update

please help

thanks
