How to get the REVIT execution path programtically?

[Anonymous]

I am using C# to develop addin for Revit 2016.

My Revit is installed under a directory. e.g.   D:\REVIT\Revit 2016\Revit.exe

How can I get the path using C#?

Normally, you have no need whatsoever to determine the path of Revit.exe to install and run your add-in.

Please work through the getting started material first of all, before asking any other questions:

That will explain all you need to know about the fundamentals, add-in architecture, installation and running.

If you really need to know the location of Revit.exe for some other reason, you can easily use the basic .NET operating system functionality, e.g., to search your file system for Revit.exe itself. 

Also, please be aware of the Revit API installation utility named RevitAddInUtility that also provides this kind of functionality:

The registry holds this information:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\Revit\2020\REVIT-05:0809

There are lots of examples on line (including from Jeremy) to read the registry.
