Just a final follow up on this, I was able to get the message boxes working the way I wanted. \:\)

The launching logic - BaseCMD - launches Kix script, which runs Install CMDs.. Install CMDs use Psexec / Kix message boxes for popup alerts to the console user throughout the installs.

Psexec is particular about wanting to work off PATH variables, or hard local paths. In my case, I went the simple route of copying my message box kix scripts to the local machine so that the PSexec calls would work.

Sample CMD:

 Code:
Pushd "\\networkserver\networkshare"
Xcopy Notice.kix C:\temp /q /y
psexec /accepteula -i -s Kix32.exe "C:\temp\Notice.kix"
popd


Sample Notice.kix:

 Code:
SetConsole('HIDE')
$MessageHeader = ' ***IT Administration is applying software upgrades to your computer*** '
MessageBox ("$MessageHeader","               Cool Nifty Software is being installed / upgraded...               ",0,60)
exit


I have a few more tests to run before I'll say it's golden, but it's looking much better now. \:\)
