I'm not sure why, but when using Killerbee's method, I get an error about the Exit command not being correct or something (I don't recall the exactly what it said). It happened after the unpacking or installing (whichever uses the little progress bar and box next to it)... Here's what I'm doing:
CODE
HKLM,"%RunOnceEx%\install5",,,"Open Office 1.1.1"
HKLM,"%RunOnceEx%\install5",1,,"%24%\install\OOo\setup.exe -r:install\OOo\setup.txt -debug"
Right after that's run, a batch file deletes my install directory and restarts my computer (after 60 seconds). Any ideas would be greatly appreciated.
