I had a similar issue. Unfortunately, the installer will not always show errors when it cannot install the Viveport Desktop app.
Here's what helped me:
Manually started (with admin rights) the Desktop app installer ViveportDesktopSetup-1.2.1.36.exe from folder C:\Program Files (x86)\ViveSetup\Updater\App\PCClient .
Looked up up the error code in the installation log file %temp%\VIVEPORT_Desktop_xxx.log (xxx is installation start timestamp).
The installer had an issue with C:\ProgramData\Package Cache which could be solved. (Microsoft Visual Studio installers provide a --nocache switch for this type of issue.)
