Visual Studio 2017 issue during extension installation

i try to install new extension on visual studio 2017 community when i go to Menu Tool>>Extensions and Updates.. i got error "Retrieving the COM class factory for component with CLSID {xxx} failed due to the following error: 8007007e The specified module could not be found. (Exception from HRESULT: 0x8007007E)"

I used ProcessMonitor To find missing DLL, I found that "C:\ProgramData\Microsoft\VisualStudio\Setup\x86\Microsoft.Vi‌​sualStudio.Setup.Con‌​figuration.Native.dl‌​l" Result:PATH NOT FOUND How to resolve this issue ?

Notes:this occur when uninstall VS 2017 RC and Install VS 2017.

According to this thread, you should first execute "InstallCleanup.exe -full" command, and then run the Visual Studio Installer to repair your VS installation.
