Installing Visual Studio 2012 Ultimate on Windows 8

Posted on

Problem :

While trying to install the visual studio 2012 ultimate trial on Windows 8 Release Preview I got the following error message

The .Net Framework installed on this machine does not meet the minimum
required version: 4.5.50709.

So I tried installing the required .net framework version, but that gave me the following error

Microsoft .NET Framework 4.5 is already a part of this operating
system. You do not need to install the .NET Framework 4.5

I am running the windows 8 release preview on a 32-bit Intel Core2Duo system, with Visual Studio Express already installed.

Can somebody please help if you have any guesses at all. This “chasing-your-tail” problem is frustrating.

Solution :

This solution worked for me for at least Express 2012 for Web on 32-bit Windows 8 Release Preview:

  1. Find HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDPv4Full node in the regedit
  2. Right click on the node, choose Permissions, then click “Advanced” button and change owner of this node to Administrators and then click OK and give Full Control permission to Administrators
  3. Change the value of “Version” parameter to “4.5.50709”

I found this instruction at . It also contains 64-bit windows registry path.

Other solutions:

Solution A)

  • Download the .NET 4.5 installer and extract it (run it with /x, or open in WinRAR, etc.)
  • Go to the extracted folder and open ParameterInfo.xml.
    Remove the TAG blockers, completely: remove the branch < blockers >.
  • Execute SEtup.exe and try to install it again.

(It worked for me in Windows 8 Ultimate Version).

Solution B)

  • Run regedit.exe.
  • Edit Framework version key.
    • WIN64-bit: Go to the following key:HKEY_LOCAL_MACHINESOFTWAREWow6432NodeMicrosoftNET Framework SetupNDPv4Full
    • WIN32-bit:Go to HKEY_LOCAL_MACHINESOFTWAREMicrosoftNET Framework SetupNDPv4Full

NOTE: You’ll need to change the permissions before you can edit anything. First, change the owner to Administrators, then assign the Administrators principal with Full Control.
– Finally, simply change the value for “Version” to “4.5.50709”.
To change permission for editing registry, in Regedit, select you key, right-click–>Permissions–>Advanced–>Owner, select Administrators, Apply. Then grand Full Control to “Administrators”

That isn’t supported and isn’t going to work. Both VS and Windows were evolving, and only a few very specific combinations of OS and IDE worked together. Since both are now RTM this should no longer be an issue, and MS are certainly not going to go out of their way to make these throwaway test platforms ensure compatibility.

If you are an MSDN or technet subscriber you should be able to download a Win8 RTM image for development purposes (testing, validation, etc). Otherwise you’ll have to purchase and install Windows 8 retail, or install VS2012 on your existing OS (Windows 7, presumably). Likewise, VS 2012 RTM is available from MSDN. Note that VS2012 only supports “Modern UI” development (or whatever it is called this week) on Windows 8 (regular .NET framework development is supported both on Windows 7 and Windows 8).

You can also get 90 day trial of Windows 8 Enterprise from here now
