To uninstall Microsoft Visual C: ​. Open Programs and Features from the Windows Control Panel (or Add or Remove Programs for Windows XP). A simple way to bring this up on non-Windows XP systems is to type 'programs and features' in the search field at the bottom of the Start menu.

• Hi Brian,

  It sounds like you installed just VSfM by itself, then installed Mono separately? Try installing from the universal installer, which should install everything required at the same time.

  There are version requirements between the various packages, and for example if you installed a mono that was much too old for a given VSfM you might run into issues. Ms publisher imagesetter when redirected using rdp for mac.

  The universal installer handles all of that for you.

• Hi Chris, Timothy, Thanks for your responses.
  I believe I am using the universal installer.
  I did it again using the link in Timothy's response.
  When prompted I chose to install Visual Studio, Android, IOS, macOS and workbooks and inspector.
  The installation was very quick (because I guess I've already installed it).
  I got a message to say the installation was successful and a button to launch Visual Studio.
  When I click on the launch button I get the same error.

  I tried installing VS 2017 Community for Mac for the first time. I am facing the same issues.
  The installation was successful but when i launch VS 2017 from launchpad. It shows the error.

  So, installing components outside of the universal installer might have introduced the problem, one that the universal installer couldn't fix automatically. One thing you could try is to uninstall everything:

  By using the uninstall script (https://raw.githubusercontent.com/MicrosoftDocs/visualstudio-docs/master/mac/resources/uninstall-vsmac.sh) or by following the steps documented, then reinstalling everything.

  Before that however, what version of macOS are you running?

• Chris, Your suggestion to try uninstalling everything has worked !! I now have Visual Studio Community running on my Mac - I guess that's what I wanted. I'm trying to work my way through a Writing Your First Application in Xamarin Pluralsight course. Thank you so much for your help. It's much appreciated. Regards, Brian.
