Yesterday tried to install ‘Security Update for Microsoft Visual Studio 2010 (KB2455033)’ via Windows update on Windows 7 Ultimate 64-bit but it failed with Code 643. Installation constantly failed with Code 643 – Some updates were not installed.
Currently Google search does not shows anything useful, however Microsoft Connect have listed 4 workarounds. I tried only last one, and it worked.
