Summarize your bug I had a problem with the EA desktop not launching so I decided to uninstall it and try to reinstall it again. The problem was, it said the program was already installed. I used the .MSI file but it didn't work, and I also removed any trace of EAdesktop on my computer from Regedit and even installed third-party apps to remove any trace but it didnt show any trace of Ea desktop on there either. Ive done almost everything that comes to mind and it just didnt work.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? Uninstall the program and try to install it again.
What happens when the bug occurs? it brings up something that says "the program is already installed" and when you click it, it just brings up your folder with nothing on it.
What do you expect to see? For this to be fixed so I can download the EA desktop again.

please fix this error I've had. I uninstalled EA desktop and now it says it's already installed even though I removed literally any trace of it from my computer. Their arent even traces being shown on third-party apps. I also used the .msi and it didnt even show up
