Error Message: Please go to the Control Panel to install and configure system components

[bryan]

I have written a batch file to run at client startup to delete an old
ptogram and add the new version:

@ECHO OFF
IF EXIST C:\iptvcheck.txt GOTO END
IF NOT EXIST c:\iptvcheck.txt GOTO INSTALL
:INSTALL
net use \\fhst-dha-app1\vol1
copy n:\batch\iptvcheck.txt c:\
ECHO PLEASE DO NOT START ANY APPLICATIONS! IPTV IS BEING UPDATED AND
WILL REBOOT YOUR MACHINE IN 60 SECONDS.
C:\Windows\System32\msiexec.exe /q /x
{5ECDB603-437C-11D2-AFC6-0060082B1429} /gf
CD n:\win32aps\iptv viewer 3.5
setup.exe /s /v/qn
GOTO END
:END

When running the batch file everything executes except the the silent
install at the end. i keep getting the message: Please go to the
Control Panel to install and configure system components. any ideas?
