I'm trying to get some batch files to run from the 'RunOnce' section during an nLite unattended install. Here's an example: %PROGRAMFILES%\Utils\shortcuts.cmd %PROGRAMFILES%\Utils\addpaths.cmd I'm getting an error message during install after adding these lines (the batch files were tested and known to work correctly). I can't remember the exact error, but I believe it was something along the lines of 'Invalid path in registry...'. This was the only change I made to the disc, so I'm assuming it must be the syntax of using the %ProgramFiles% system variable. Do lines need to be in double quotes, do I need to escape the double quote characters? What's the syntax for running batch files from RunOnce? Also, I wasn't sure if nLite did anything to these lines to prepare them, etc...
