Lookup Dynamics GP install location from registry key

You should never assume that Dynamics GP has been installed in the default location. Almost always it will be, but sooner or later you will find a site or development machine where it is different. It is a good idea to check the machine registry for the application folder(s).

You should also not assume there is only one instance of GP! There may be multiple instances installed, see the note later on in this post about checking for instances. The format of the registry keys has evolved through the versions, to support new features (instances) and versioning.

64-Bit Windows Operating System

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Business Solutions\Great Plains\v14.0\1033\DEFAULT\SETUP
32-Bit Windows Operating System
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Business Solutions\Great Plains\v12.0\1033\Default\SETUP

The keys found under this registry location are as follows (on my machine):

Registry Keys GP2015 Listing

Note for GP 10 version

The path omits the version number:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Business Solutions\Great Plains\1033\Default
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Business Solutions\Great Plains\1033\Default

Note for GP 9 version

Drop the 1033:
HKEY_LOCAL_MACHINE\Software\Microsoft\Business Solutions\Great Plains
HKEY_LOCAL_MACHINE\Software\wow6432Node\Microsoft\Business Solutions\Great Plains

For GP2010 onward

The convention is to embed the GP version number, v14.0 in this example, into the path. The “v14.0” part of the path is dependant on the version of GP that you are running or targeting, Victoria Yudin has a good lookup for these on her site:
Dynamics GP build numbers and service packs

Victoria Versions GP

Check for multiple instances

In the registry path, “DEFAULT” refers to the instance of GP, so if there are multiple instances the path would look like this:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Business Solutions\Great Plains\v14.0\1033\Inst0X\SETUP

Where “Inst0X” is the instance name, note in the image below that there is an instance name folder too! What at first glance is a simple task just became so much more difficult, didn’t it?!

Then it all goes wrong…

But you may notice that in the earlier values, the version of GP was listed as 14.00.0726 and yet if I look at the version from the application I get listed 14.00.0952. This is because we copy deploy GP, one of the pitfalls of this approach is that this means the registry is not maintained by the setup installer correctly when new versions are rolled out.

GP Version

Although this does not change the location of the application, I thought it worth pointing out before the reader runs away with using the registry as the source of the truth for other facts, it can be stale information!
