Creating Windows Remote Commands

I have found creating Windows Remote Commands very difficult, because there is no logging and no way (that I can tell) to discover what the error is when a command fails to function as expected.  Has anyone found a way to capture error data during Remote Command testing?

For example, I'm trying to create a Remote Command that does an unattended installation of the Sun Java update.  This command works perfectly from the commandline:  "C:\Users\pauls.CAMPUS\AppData\LocalLow\Sun\Java\jre1.6.0_18>jxpiinstall.exe /s /v" /qn[ADDLOCAL=ALL][IEXPLORER=1][MOZILLA=1][REBOOT=Suppress][JAVAUPDATE=1][EULA=1]"

When trying to translate that to a remote command, the double quote in the middle becomes a pesky varmint.  I tried replace it with chr(34), but that didn't work.  What's really frustrating is that the remote command runs, the agent wakes up but nothing happens and no errors are generated to give me a clue what the problem might be.

Any tips or tricks on creating and troubleshooting Windows Remote Commands would be most appreciated.
