When starting to install Visual Studio 2012 Update 4 I first get this warning
Installation errors may occur because the security certificate updates
that are required to install some Visual Studio components cannot be applied to this computer.
This can occur when you are not connected to the Internet or when a group policy setting on your computer prevents Visual Studio from
automatically applying the security certificate updates.
If you choose to continue,
some Visual Studio features may not work as expected. For more information,
see http://go.microsoft.com/fwlink/?LinkId=317796.
Then when installing I get to the section for acquiring Windows App Certification Kit x64 Patch. At this point the installation process stops and asks me if I want to get the it from the directory with the installation file or from the internet. I choose the installation directory. It spins for a time then ask me the same question again. When the first attempt fails I say get it from the internet. However that fails as well. Then the cancellation of setup leaves 1/2 of the installation completed and the other half not even attempted.
I uninstalled the VS 2012 Update 4 installation. Then I got the iso for the stand alone installation. However when I tried to burn it to a dvd, I go the error, file format incompatible. When we have seen that error here before, it meant the the attempt to download the file to the navy's machines had corrupted the file. It was necessary to download the file from outside of the Navy network, (which as a contractor I don't have the rights to do.)
So I tried to continue working with the older version of VS 2012. Now it reports every solution as "incompatible". So I can't do any work.
I am attempting to install VS 2012 Update 3 in hopes of getting the IDE to once again recognize my projects. However I now get the warning
Microsoft Root Certificate Authority 2010 or 2011 is missing
and can cause installation failures for some signed packages. For more info, see http://support.microsoft.com/kb/931125.
This will end up leading to the same error that started this. So I went to the link that they listed and instead I get a Microsoft Support empty search results page.
I tried the install anyway and sure enough this led to the same error that started this.
However after carrying out the partial update of my Visual Studio, I was hoping that enough had been done to allow my projects to be opened again. That was not the case.
So I did a search on the kb 931125. It took me to this link http://answers.microsoft.com/en-us/windows/forum/windows_7-windows_update/windows-7-64-bit-not-being-offered-kb931125-roots/aae0741d-df61-4a28-aaa3-d77c80929af1?auth=1 This link provided a link
to download a file to update the Microsoft Certificate, here: http://download.windowupdate.com/msupdate/update/v3/static/trusted/en/rootsupd.exe But that resulted in a 503 error, when attempting to load.
I posted this on a Visual Studio Set-up forum page, but as usual in that forum I go no help at all.
Update: I ran a repair from Add/Remove Programs. After running for 1.5 hours I am now allowed to open my project. And itsays it has Update 3 on there. Hurray!!!
