Usually when the add-in shows in Word under Options > Add-Ins, under Inactive, we would verify what 'Type' the GP Add-In is showing as, for example mine shows as a 'COM Add-in', then we'd want to select 'COM Add-ins' from the drop-down list next to 'Manage:' at the bottom of the window, then click 'Go...' and then in the list of 'COM Add-ins', we'd want to put a check-mark next to 'Microsoft Dynamics GP Add-in for Microsoft Word' and click OK, which should then show the GP Add-In as a active add-in in MS Word.
Other things to verify if this doesn't resolve the issue:
>>The default path for the Dynamics GP Add-In for MS Word is C:\Program Files (x86)\Microsoft Dynamics\Report Templates\, if you browse to this directory, do you see 2 .dll files, a .manifest file and then a .vsto file?
If you see these four files, cut/paste them into a backup folder, then in Control Panel > Programs > Programs and Features, run a Repair against the 'Microsoft Dynamics GP Add-in for Microsoft Word', which should re-create those four files, then launch MS Word and see if you see the GP Add-in, even as a inactive add-in now, or not at all.
>>Other prerequisites that the GP Add-Ins rely on, that we've seen have to be uninstalled and reinstalled to get the Add-Ins to work are:
a. Uninstall the GP Word Add-In
b. Uninstall the Visual Studio #### Runtime (if applicable)
c. Uninstall the Visual Studio Tools for the Office System 3.0 Runtime (if applicable)
d. Launch the install of the GP Word Add-Ins again, which should prompt to install any missing pre-requisites as needed.
e. Once the install of the GP Add-Ins for MS Word complete successfully, go through the same steps mentioned previously to enable the add-ins and the Developer tab in MS Word.
>>We've also seen where we've had to completely uninstall MS Office (to include Word) and reinstall it to get the GP Add-Ins to work, as there are Registry settings also that the GP Add-Ins rely on and if those are not setup correctly, the installation could seemingly fail or not work correctly.
>>Lastly, verify the following:
a. Go to Start | Run and type regedit.
b. Go to the following location:
HKeyCurrentUser\Software\Microsoft\Office\Word\Addins\Microsoft.Dynamics.GP.BusinessIntelligence.BITemplateMapping
c. Verify the LoadBehavior key is set to 3. (i.e. 0x00000003 (3) )
d. Please also verify the path to the Manifest is correct. It should point to the Microsoft.Dynamics.GP.BusinessIntelligence.BITemplateMapping.vsto file. For example, mine shows as C:\Program Files (x86)\Microsoft Dynamics\Report Templates\Microsoft.Dynamics.GP.BusinessIntelligence.BITemplateMapping.vsto|vstolocal
I also wanted to mention that the Microsoft Dynamics GP Add-in for Microsoft Word is User Profile specific. Therefore, this add-in needs to be installed for each user that is going to be creating new Word templates and/or adding data sources and fields to existing Word templates.
I mention this just in case you're installing this logged on as your domain\userA account, but then having domain\userB look for it in their MS Word.
Let us know what you find out.........Thanks
