I am attempting to install Delphi 2007. I have been given a slip file. However I am being prompted to enter a serial number by the installer.
A typical reason for having a slip file could be because you obtain your license from the Belise license server. If so the way to proceed is to ensure that your installation files are in a writable directory, for example on a network share. This could mean that you need to copy the contents of the installation DVD to this directory, if you have bought Delphi 2007 on a DVD.
Copy the slip file into the same directory as the setup.exe. The installer will read the slip file will then not prompt for the serial number.
