Unable to load add-in registered under HKLM for MS Project 2007.

Question

Hi,

I have developed an Add-In for MS Project. The add-in is working fine for MS Project 2010 as the add-in is registered under HKLM, but when i try to load an add-in for MS Project 2007 the "LoadBehavior" value changes from 3 to 0, so i was trying apply the above mentioned hofix (office-kb976477) in order to get add-in worked for MS Project 2007.

But i am not able to install this hofix on my machine, it shows the message "The expected version of the product was not found on the system." when i try to install the hotfix.

I tried to resolve the problem by installing "Microsoft Office suite Service Pack 2" as it is mentioned at support.microsoft.com/.../976477 and then applied the hotfix but it gives the same message.

There is Microsoft Office Standard 2007 and Microsoft Office Project Standard 2007 installed on my machine.

Any idea/suggestions?

Thanks,

Answer 1

have you tried installing SP3 for project? http://www.microsoft.com/en-us/download/details.aspx?id=27811 

Answer 2

Thanks DaminD for reply but still not able to load an add-in even after installing SP3 for project at  http://www.microsoft.com/en-us/download/details.aspx?id=27811 .

And the behavior is same as it was that is the "LoadBehavior" value changes from 3 to 0 in the registry for MS Project 2007.

Also in "COM Add-Ins" dialog of MS Project, my add-in remains unchecked and its load behavior is as,

Load Behavior :  Unloaded.

Answer 3

have you tried setting EnableLocalMachineVSTO to 1 for your project in registry?

Answer 4

Yes, i added EnableLocalMachineVSTO to the registry at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\12.0\Common\General

and set it to 1, the add-in is getting loaded and working fine now.

Thanks DamianD for your suggestion.
