Microsoft Dynamics GP 2013 .MSP Patch Files Removing Information from Dex.ini and Registry

We have identified an issue with Microsoft Dynamics GP 2013 where the .msp files are removing registry entries and part of the Pathname= line in the Dex.ini when you RE-APPLY a patch.  The first install of the patch works fine.  The issue comes into play if you reapply the patch again on either a single instance or multi-instance.  The Country and System Database Name get blanked out in the registry.  The Pathname= line in the Dex.ini gets modified.

The current workaround when re-applying the .msp to a specific instance of GP 2013 is to do the following: 

1. Click Start, click Run, type regedit, and then click OK.

2. Locate and then click the following registry subkey:
Microsoft Dynamics GP 10.0 and later versions

32-bit environment
HKEY_LOCAL_MACHINE\Software\Microsoft\Business Solutions\Great Plains\1033

64-bit environment
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\Business Solutions\Great Plains\1033

3. Expand the folder for the instance of Microsoft Dynamics GP you want to patch.

Note The DEFAULT folder is for the default installation. The Inst01 folder is for the second instance of Microsoft Dynamics GP. For example, if you want to patch the second installation, expand the Inst01 folder.

4. Click the SETUP folder, double-click the Product Code, and then copy the code.
5. Exit Registry Editor.
6. Open up a Command Prompt by right-clicking on it and selecting Run As Administrator.
7. To install the .MSP file, type the following, and then click OK:

C:\updatename.msp /n {E979C594-95F9-4E3A-985D-A1DFDF403227}

Note Replace "C:\updatename.msp" with the path to the .MSP file and the name of the .MSP patch file. Replace "{E979C594-95F9-4E3A-985D-A1DFDF403227}" with the Product Code that you copied in step 4.
 

The current workaround when re-applying the .msp to all instances of GP 2013 on a machine is to do the following:

1. Open up a Command Prompt by right-clicking on it and selecting Run As Administrator, type in the following:

msiexec.exe /p C:\updatename.msp

(Example:  msiexec.exe /p C:\ MicrosoftDynamicsgp12-kb2799678-enu.msp)

Note Replace "C:\updatename.msp" with the path to the .MSP file and the name of the .MSP patch file.

2. Click OK.

Thank You!
