Changes

Many of the silent installs are listed with %SOFTWARE% as a placeholder for the location of the installation files. If your installation files are for licensed software then there is probably something in the license that says you have to control access to the install files. If you set the %software% environment variable globally then any command prompt will reveal teh the location of these files. You can prevent this by setting the variable in the wpkg-start.bat batch file so that it only affects that "session". It also keeps all the environment variable settings for WPKG as part of the WPKG script and ensures the variable is set before the script runs.
