UI Flow installer error VCRedist64

I am unable to install the UI Flow desktop components.  The following is from the install log:


[2444:5F8C][2020-03-25T14:06:29]i301: Applying execute package: VCRedist64, action: Install, path: C:\ProgramData\Package Cache\B87C38D093872D7BE7E191F01107B39C87888A5A\VC_redist.x64.exe, arguments: '"C:\ProgramData\Package Cache\B87C38D093872D7BE7E191F01107B39C87888A5A\VC_redist.x64.exe" /install /quiet /norestart'

Points to a newer version of the VCRedist64.exe on my system (I installed VS2019 last week).  What I don't know is what version is UI Flow expecting to use, and how does that interoperate with the new universal C runtime?



Thank you,

@kenjensen I was facing same issue. I end up uninstalling Microsoft Visual C++ 2015-2019 REdistributable(x64) program through control panel. 

Rerun Setup.Microsoft.Flow.UIflow.exe again, and this time was successful. It end up installing the earlier redistributable program i had removed.
