Skype For Business CU1 (September 2015) fails

To make a long story short - make sure you have atleast 32 GB free disk space when running Security Updates for Skype for Business Server: September 2015

KB3097645 fails even at the second attempt.

The fix KB3097645 will run an Install-CsDatabase command to patch the database.

If you look at the log found in the same directory as your SkypeServerUpdateInstaller.exe
e.g. C:\temp\Skype_patchinstallerlog-FE01-[2015-12-08][14-00-01].txt

You will find the following error messages:

[12/8/2015 2:00:01 PM] Executing command: msiexec.exe  /update "C:\temp\Server.msp" /passive /norestart /l*vx "C:\temp\Server.msp-FE01-[2015-12-08][14-00-01]_log.txt"
[12/8/2015 2:00:23 PM] ERROR 1603: Server.msp had errors installing.
[12/8/2015 2:00:41 PM] ERROR: SkypeServerUpdateInstaller failed to successfully install all patches


If you look in the file LCSSetup_Commands.txt found in the user profile
e.g. C:\Users\kressmark\AppData\Local\Temp\LCSSetup_Commands.txt

You will find a more understandable error message:

Install-CsDatabase : Command execution failed: Install-CsDatabase was unable to find suitable drives for storing the database files. This is often due to insufficient disk space; typically you should have at least 32 GB of free space before attempting to create databases. However, there are other possible reasons why this command could have failed. For more information, see http://go.microsoft.com/fwlink/?LinkId=511023

The solution is of course to simply free up some disk space or expand the disk.

Happy patching!

  1. Thank you, that worked like a charm.
    Increased the disk space to above 32 GB and rerunning the setup installed the missing component and we were able to get the FE service back.
    Its amazing how MS do not list this as a prereq.
