Hi there,
I'd suggest downloading Ccleaner and using it to uninstall any possible remaining files from the EA app from your PC. Also, you could use it to clear temporary and cached files.
For instructions on how to use Ccleaner to uninstall apps, click here.
While we suggest using CCleaner, EA does not provide user support for this program–use it at your own risk. Please follow any installation guides straight from CCleaner when installing and performing program set-up. You can find help on CCleaner’s support page.
Once that's done, please try a clean install of the EA app. For further information regarding EA app error codes, please see: How to troubleshoot common EA app error codes
