[wpkg-users] Program installs fine when calling js, but not when through service

[Kevin Keane]

I just had the same phenomenon happen to me. It turns out that the reason is actually embedded in a comment in wpkg.js: if the program you call from within your .JS produces more than approximately 4kb of output to stdout, a buffer fills up and that program stalls.

It appears that this has to do with how Microsoft implemented Javascript (I didn't look too deeply into it, just found the comment in wpkg.js ).

The solution is to make sure your batch file produces less output than that. Look into quiet output and/or redirecting output to >NUL

  I have a program that uninstalls MSDE 1.0 and reinstalls it after a computer name change. This is used for a few computer labs. I'm having a real difficult problem (First time user of wpkg and I've spent more time than I'd like to admit to get this to work!), first, here is the batch file I'm running:

REM ======REMOVE======

NET STOP "MSSQLServer"

taskkill /F /IM "sqlmangr.exe"

start /wait %systemdrive%\WINDOWS\IsUninst.exe -msql70.mif -f"%systemdrive%\MSSQL7\uninst.isu" -C"%systemdrive%\MSSQL7\sqlsun.dll" 
-y -a

REM ======INSTALL=====

copy \\205.189.30.226\WPKG\Programs\msde\mike_msde_setup.iss %windir% \\205.189.30.226\WPKG\Programs\msde\x86\setup\setupsql.exe k=Dk -s -m
-f1 "%windir%\mike_msde_setup.iss"

REM ======DONE======

When running the batch file directly on the UNC share, it will complete fine. When I run wpkg.js through cscript with the same command in wpkg it will complete fine. When I let the service run, it never completes, it gets through the uninstall, and I see the install exe running which never ends and just sits there. WPKG is set to run as the same account I've tried the batch/direct cscript js call from.

Why is this?
