How can I get the Tridion Installation Path?

Question

We have a SDL Tridion installation on Windows Server 2008 R2. We want to get the path of the Tridion Installation home folder programatically in the Event System.

Is there an Environment Variable or setting we can read through TOM.NET API or C# code to get this?

Answer 1

You can us the below generic code to get the installation path of SDL Tridion (it looks you are using SDL Tridion 2011 as specified by the question tag) regardless of the fact whether you are using a 32-bit OS or 64-Bit OS:

      private string GetTridionInstallPath()
      {
         string output = string.Empty;
         string regKeyPath = string.Empty;
         if (Environment.Is64BitOperatingSystem)
         {
             regKeyPath = @"Software\Wow6432Node\Tridion";
         }
         else
         {
             regKeyPath = @"Software\Tridion";
         }
         RegistryKey regKey = Registry.LocalMachine.OpenSubKey(regKeyPath);
         output = regKey.GetValue("InstallDir").ToString();

         return output;
      }

I hope it helps

Answer 2

You can use:

• Tridion.ContentManager.ConfigurationSettings.GetTcmHomeDirectory();
• Environment.GetEnvironmentVariable("TRIDION_CM_HOME");
• Any of the other methods already mentioned.

If you have the option, use the GetTcmHomeDirectory() method, since that's the one used by Tridion itself.

Answer 3

I think the following environment variable will work.

%TRIDION_CM_HOME%

You can get this in C# using Environment.GetEnvironmentVariable

Answer 4

I refer you to the "GetTridionInstallPath" recipe contributed by Frank van Puffellen to the Tridion Cookbook at Tridion Practice. If you also include the comment by Peter Kjaer, it covers all the techniques mentioned here so far.

It's actually the first hit if you Google for "get tridion installation path".
