Invalid license configuration (.slip) file

Abstract: This error occurs when the installer find an invalid activation file

Q. I am running the install for Rad Studio/C++ Builder or Delphi, and after entering my name and company name:

I get the error "Invalid license configuration (.slip) file"

How do I fix this?

A. This error is caused when an activation file (reg*.txt) or slip file (*.slip) file is found in the same directory as the installer and does not apply to the current installation. To resolve the problem copy the installer to a new folder which contains no other files.
