|"I tried downloading it, but AL isn't letting me run it."|
This is what I mean by being specific, what are you refering to by saying "it"
If others had posted after me, as has happened above, no one knows what "it" is.
I assume you mean malwarebytes
Did you try these as ways I posted earlier?
"If it installed but will not run, navigate to this folder:
2: C:\Programs Files\Malwarebytes' AntiMalware
At the top of the page, Tools > Folder Options > View, click > Show hidden files and folders and untick > Hide extensions for known file types.
Rename all the .exe files in the Malwarebytes' Anti-Malware folder and try to run it again."
Another way, if after doing the above, try all of the above with malwarebytes in Safe mode.
