RBAViewer location change

RBAViewer has moved from <installdir>\tools\servertools\rbaviewer.exe. It’s now located in the Configuration Manager console directory.

After you install the console, RBAViewer.exe will be in the same directory. The default location is C:\Program Files (x86)\Microsoft Endpoint Manager\AdminConsole\bin\rbaviewer.exe.

Updated SCCM Client Deployment Prerequisite

The Configuration Manager client requires the Microsoft Visual C++ Redistributable component (vcredist_x*.exe). When you install the client, it automatically installs this component if it doesn’t already exist. Starting in this release, it now uses the Microsoft Visual C++ 2015-2019 Redistributable version 14.28.29914.0. This version improves stability in Configuration Manager client operations.

  1. Thanks for sharing new features in TP2105. I wanted to try the same at home lab. I never had any issue with TP install before. With this TP2105, I am getting this error when, I try to download the preview.

    ERROR – Failed to download AdminUI content payload with exception. The underlying connection was closed. An unexpected error occured on a send.
    Failed to call AdminUIContentDownload error = 2146233079

    This error is from dmpdownloader.log file.

    Appreciate, if you can help me.

  2. Thanks to your reply. This is home lab environment. All firewall disabled. I tried the following – still same error.

    Uninstalled TP2104
    Restarted and Installed TP2103 Base Version
    Ran check updates – still same error.

    If there a way to manually download the update and continue with the install like, we would do for Current Branch early release?
