(where the executable is "sandboxed" in a virtual user context/file system) Would this tool be something like Avecto DefendPoint or Bromium? It should also be noted that we are using a tool similar to AppLocker for application whitelisting and have whitelisted the (4) Lync Web App executables (LWAPlugin.exe, LWAVersionPlugin.exe, AppSharingHookController.exe and AppSharingHookController64.exe).Īny assistance or guidance would be greatly appreciated!!ĭid the "strange problem with sudden prompting" only happen after this "tool like AppLocker" was introduced, or was upgraded, or changed ? What is really strange is the "D:\Users\rtbldlab\AppData\Local\." program name which seems to indicate a problem with the MSA package. Issue for both the 32-bit and 64-bit Lync Web App Plug-in MSI installation packages.
#Download microsoft lync web app plugin install
To install as long as we add *. to our trusted sites list and provide UDP/TCP firewall domain access for the plug-in executable (lwaplugin.exe).Īs seen in the attached screen shots we are seeing a strange UAC prompt during the MSI plug-in install which the user initiates after downloading the MSI from Lync meeting web page () the first time they go to join a meeting. We were told that the plug-in is a per-user installation and does not require admin rights We are running into a strange problem with the Lync 2013 Web App Plug-in all of a sudden prompting our users for credentials via UAC when the plug-in installs.
