Yesterday I installed Visual Studio 2010 SP1 on my home computer. After the installation I wanted to upgrade MVC3 to the RTM version (I had the RC version installed), so i uninstalled the RC and downloaded the new version. The installation came half way, then stopped, in the log file i found this:
Installation failed with error code: (0×80070643)
Not very helpful, but at least something to google. Then I found this blog post. The author describes pretty much the same issue that I had, so I did what he suggested, unpacked the installer using 7-Zip and installed the MSI packages in the following order:
- 1. aspnetwebpages.msi
- 2. aspnetwebpagesvs2010tools.msi
- 3. aspnetmvc3.msi
- 4. aspnetmvc3vs2010tools.msi
- 5. nuget.msi
This happily installed MVC3 without complaining. Thanks Michael!
