How can i retrieve devenv.exe path for a vspackage installation?

Question

I'm following this tutorial http://msdn.microsoft.com/en-us/library/bb458038.aspx to create a VsPackage Setup. In the part of the creation of an installer class appears a reference to this location in the registry "SOFTWARE\Microsoft\VisualStudio\9.0\Setup\VS\EnvironmentPath" where it says that contains the devenv.exe location. I explore the registry and that location doesn't exist. What is the correct location of the devenv.exe path? I'm using Visual Studio 2008

Answer 1

I'm sharing my code. It’s working for me.

String path = GetDevenvPath("9.0"); // For VS 2008 
Or
String path = GetDevenvPath("10.0");  For VS 2010

private String GetDevenvPath(String vsVersion)
{
   String vsInstallPath = (String)Registry.GetValue(String.Format("HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\VisualStudio\\{0}", vsVersion), "InstallDir", "");
   return vsInstallPath + "devenv.exe";
}

Answer 2

You need to access HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Setup\VS\EnvironmentPath on 32bit machines and HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VisualStudio\9.0\Setup\VS\EnvironmentPath on 64bit machines.

If you write a 32bit program that reads the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Setup\VS\EnvironmentPath you will be automatically redirected to Wow6432Node on 64bit machines by Windows.
