Lync and Skype for Business Desktop Client Versions (MSI/C2R)

We receive a few number of questions related to the different versions of Skype for Business clients that are available.

If you already use Office 365 then probably you have the Skype for Business  2016 C2R (Click-to-Run).

Skype for Business 2016 C2R (Click-to-Run)

This is the version that is available in Office 365 and it contains the latest features, moving forward this version is also recommended for OnPrem (Lync Server 2013 and Skype for Business Server 2015).

Skype for Business 2016 MSI

This version is the Volume License version and doesn’t include all the features available in SfB 2016 C2R.

Both versions are supported but it’s recommended to use the SfB 2016 C2R version instead.

How to check the version

Please note that the version displayed in the Help > About is the MSO version and not the SfB Version.

To check the installed update we can use the following PowerShell cmdlet:

Get-ItemProperty “HKLM:\Software\Microsoft\Windows\CurrentVersion\App Paths\Lync.exe” | ForEach-Object {Get-ChildItem -Path $_.Path -Recurse lync.exe | Select-Object -ExpandProperty VersionInfo | Select FileDescription,ProductVersion}

Alternatively, go to the Tracing Folder and check the ETL filename:

%userprofile%\AppData\Local\Microsoft\Office\16.0\Lync\Tracing
