About Windows Installer, the .NET Framework, and Visual Studio.
Now that Visual Studio 2012 and .NET Framework 4.5 have been released, some customers are wondering if they need to uninstall the Visual Studio 2012 Release Candidate (RC) first before upgraded. In general, the answer is “no”. VS2012 RC will upgrade to RTM, but there are a few things to note:
For more information about compatibility, see our compatibility page on the Visual Studio website.
If you need to uninstall VS2012 RC, we have posted instructions to KB2744926. For the most part, you only need to remove the main program entry in Programs and Features. While we have done a lot to reduce the number of “ARP” entries, some still remain from external partners which are not ref-counted in VS2012.
While it may not be supported, I managed to successfully update from VS2012 Ultimate RC to Premium RTM.
Interesting, I went from Ultimate RC to Premium RTM, and it seemed to work just fine.
My solution to this for the time being was to change the folder name of the item template in the "C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE\ItemTemplates\CSharp\Web\1033\" folder from WebJScript to WebJScript.zip and then rebuild the cache via devenv /installvstemplates from the Visual Studio Command prompt.
It doesn't seem like this is long-term fix, and I was wondering if you had a suggestion for this.
where are the steps to perform an upgrade from VS 2012 RC to RTM?
@Ali, just run the VS2012 RTM installer. Upgrade is automatic.
I have had the same issue. thanks for your workaround.
I tried to upgrade to RTM Professional from RC Professional and the installer fails and 2012 RC fails to load many packages. I attempted to uninstall RC but the RC installer fails. I got a bit further with the RTM installer by first uninstalling .NET 4.5 RC and installing .NET 4.5. The RTM installer reboots the machine twice but on the second reboot it fails (looks like the Windows installer crashes) on installing the IDE shell. I was using the web installer and next I'll try the DVD installer. Any more suggestions - I'm not able to use VS anymore?
@Ken, can you provide more information about the failure? What was the error message? Can you also run http://aka.ms/vscollect and post %TEMP%\vslogs.cab to an Internet share so we can review what happened?
I had the same issue as Jeff Woodard and his fixed worked
