Hi. I've managed to find silent install options for Opera. It is as follows:

start "operainstaller" /MIN "%wpipath%\Install\opera11-uni\opera.exe" /install /silent /launchopera 0

The command works fine from the command prompt (with the wpipath changed, of course) but WPI immediately gives Failed when executing the command. Is it so that the WPI doesn't support executing the Windows' integrated START command? Because other commands that use this START, fail in WPI as well. Also, del command isn't working either. Do I have to create a .bat file to execute basic commands like start or del, or does WPI in matter of fact support those commands after all? Also, I'm fine with executing those commands from .bat files IF I could just make the .bats run silently, or at least minimized.

Thanks in advance for your help. Using the latest WPI.

Use the built in delete command

{DELETE} C:\file.exe

I added a new command, {START}, and sent you the latest beta. Try it with it.

{START} "operainstaller" /MIN "%wpipath%\Install\opera11-uni\opera.exe" /install /silent /launchopera 0
