Lync 2013 restart system after installing

Hi everyone,

We got some problems when deploying Lync 2013 to our test-Clients.

I´ve created a SCCM 2007 Package with two programs.

1. x86\setup.exe /adminfile Config.MSP

2. A batchfile will delete the autostart of Lync and set the shownfirstrunoptin regkey

reg delete HKCU\Software\Microsoft\Windows\CurrentVersion\Run /v Lync /f
reg add HKCU\Software\Microsoft\Office\15.0\Common\General /v ShownFirstRunOptin /t REG_DWORD /d 1 /f

The deployment works fine. Lync will be installed with the correct .MSP Settings and the Batch will be executed. But after that every Client will automatically restart. Is there any Option to supress the restart?

Thanks a lot.

Regards, Michael
