Can't Login! - Verification Failure for Client Files

Hi, I have found the solution.

For non-Steam users who play standalone, right click the ‘EVE Launcher’ icon and go to ‘Properties’.
Next, open the ‘Compatibility’ tab and choose ‘Run this program as an administrator.’

After saving by pressing ‘OK’ open the Eve Launcher as usual and the system will ask you to click ‘Yes’ to accept to open the application with Administrative powers, and your EVE client should run now after clicking an EVE account to log in.
