"Click to Join" fails to invoke Skype for Business on computers that use Application Virtualization
- Exit all Internet Explorer(iexplore.exe) instances by using Task Manager.

Method 2Install the latest Hotfix for App-V.
Note If there are no Internet Explorer app-V add-ins, Method 1 or Method 2 is a safer route.
App-V 5.0 Service Pack 2 and later versions have enhanced “Dynamic Virtualization” by extending support to Shell Extensions, Browser Helper Objects, and Active X controls to be virtualized and run with virtual applications. The registry values under the HKLM\Software\Microsoft\AppV\Client\Virtualization subkey are used to control this feature.
Why is Office C2R and SharePoint Integration broken when App-V 5.0 SP2 or later is installed on the system?
The ProcessesUsingVirtualComponents registry value specifies a list of process paths that are candidates for using dynamic virtualization (supported shell extensions, browser helper objects, and ActiveX controls). Only processes whose full path matches one of these items can use dynamic virtualization.
By default, Explorer.exe and Internet Explorer are listed there. Therefore, when the iexplore.exe process runs, it has the APPVEntsubsystem32.dllloaded in Internet Explorer. When Office C2R detects that APPVEntsubsystem32.dll is loaded into Internet Explorer, it does not load jitv.dll or APPVISVSubsystem32.dll into Internet Explorer. As a result, there is no registry redirection support.
