WiX Toolset installs VC++ redistributable (x86) 2015 too slowly

I wrote a WiX Toolset Setup to install an application which requires the VC++ redistributable (x86) 2015. Everything works fine, but when vcredlist_x86.exe is launched, it installs the Package too slowly, it takers about six minutes !

If I run the vcredlist in standalone mode, it still takes six minutes, as timeline shows:

What could be the reason, and how this problem could be solved?

The reason for VC++ redistributable taking 6 minutes is probably caused by issues with Windows Update on the computer you are running the installer on.

The VC++ redistributable uses the WIX burn engine (part of the WIX Toolset). During the installation process the WIX Burn engine will try to pause automatic updates. This line in the log file indicates pausing automatic updates has failed after taking approximately 6 minutes to timeout:

[1254:1CC0][2017-05-29T11:02:52]w308: Automatic updates could not be paused due to error: 0x80080005. Continuing...

Error code 0x8008005 is Windows COM error CO_E_SERVER_EXEC_FAILURE, which translates to "Server execution failed". An explanation of why this error can occur can be found in the article When CoCreateInstance returns 0x80080005 (CO_E_SERVER_EXEC_FAILURE).

Suggest looking more closely at Windows Update on the target computer to see what is going on.
