Why will it not let me in studio having an error pop up?

When I try to get in studio it says

Unable to install Roblox Studio

Please make sure you have write access to this directory.

If Roblox is already installed to this directory please delete it and download a different version

I have deleted studio and reinstalled it over and over and it won't work

Try updating your device, this is a common issue with outdated devices. What device are you on btw??
