Can't download the creative cloud app on desktop because of "an installer being open" when there is not installer open
I use a MacBook pro with the latest updates and i have recently tried to download the creative cloud onto my computer for a free trial and it downloaded but i couldn't use all of the apps so I deleted all of the software off my computer and then I tried to download it again. when i downloaded the creative cloud installer i opened it and it came up with that it couldn't open because there was an installer that had to be closed but i didn't have one open. what can i do to fix this because i can't get onto the creative cloud app.
