    do you have a C:\users\YourUsername\.RapidMiner5 folder? If you do, please create a backup, then delete it and try to start RapidMiner again. If you do not, make sure your user account actually has write permissions.
    If the above does not help, and there indeed was a .RapidMiner5 folder, try deleting the 'lastversion' file in it and start RapidMiner again. If that also does not help, please open the file with an editor (like Notepad) and post the content here.
