In this example I will run a virus clean up tool
1. get the TSC utility from Trend - http://www.trendmicro.com/download/dcs.asp
2. pack the 3 files using iexpress utility (packed with windows, just run: iexpress and follow the steps for a silent install, and choose to run as installer tsc.exe) I name the new file as tscc.exe
3. in lansweeper I use the following action:
cmd.exe /K \\filer\share$\Lansweeper\psexec.exe -c -f \\{computer} \\filer\share$\Lansweeper\tscc.exe
This way you can pack a lot of scripts or utilities (even if they need several files) to run silently.
