Visual Studio Extensions not installing

earlier, I wanted to add an extension called "SemanticColorizer" to visual studio 2017, So I downloaded it, and then I closed visual studio to install the extension. I didn't get the VSIX extension installer, I got an error saying :

Retrieving the COM class factory for component with CLISD {177F0C4A-1CD3-4DE7-71DBBB9FA36D} failed due to the following error: 8007007e The specified module could not be Found. (Exception from HRESULT: 0x8007007E).

Up to now, I have tried restarting my computer, downloading SemanticColorizer.vsix from the visual studio marketplace, And installing other extensions(That also won't install).
