The best method to completely delete Racelabs from the computer is to delete its folders. Here are the required steps and locations.
Sometimes a full delete and reinstall of Racelabs will fix any issues.
1.Close the Racelab app if it is open
2.Open C:\USERS \(Your name)\DOCUMENTS\ and delete the Racelabapps folder
3.Open C:\USERS \(Your name)\APPDATA\LOCAL\ and delete the Racelabapps folder
4.Open C:\USERS \(Your name)\APPDATA\ROAMING\ and delete the Racelabapps folder
5.Delete the Racelabapps desktop shortcut
6.Restart the computer.
7.Download a new installer from https://racelab.app
Note: If you don't see the "appdata" folder, open "c:\users " and look at the upper part of the folder. Click on "Show" and then on "Hidden Items" you should then see the "appdata" folder in your file list.
Note: "(your name)" in the above places is your Windows username.
