Add-ins tab is missing in Outlook 2007

Hi all,
I have a custom addin that works for outlook 2003 or above. I have installed it and working in several machines with outlook 2003 and 2007 (with xp and vista), but.. there is one pc with outlook 2007 sp2 /xp that doesn't display the tab "add-ins" in the ribbon (in the mail inspector), so , I can't access to the addin button.
I create from my addin a command in the command bar, so, it  should display the addin in the "add-ins" tab in the ribbon.

I'm new with addins, so I don't know how to debug this issue...
I use in the addin redemption and .net 1.1.

I appreciate any help to solve this.
Thanks!!
Leo

Could be one of many issues ...

1. In Outlook go to Tools, Trust Centre, Add-Ins and check if your add-in is not getting disabled

2. Is it a VSTO add-in or a COM add-in ? if VSTO you can set some environment variables to get more infomation about the problem that is preventing it from loading ...

Go to  Control Panel, System, Advanced, Environment Variables, System Variables section
Add New
      VSTO_LOGALERTS = 1
      this will add to a log file in the add-in install folder (manifest file name .log)
Add New
      VSTO_SUPPRESSDISPLAYALERTS=0
      this will display the problem on the screen

3. Check the system registry key for your add-in
For VSTO this will be in under HKEY_CURRENT_USER and for COM it will be undr HKEY_LOCAL_MACHINE. Then SOFTWARE.Microsoft/Office/Outlook/Addins/your add -in
Set the value for LoadBehaviour is set to 3

4. Try running Outlook as administrator to test if it shows your add-in

Note that before you do the above you misy close Outlook and re-start it afterwards - check in task manager that there is no running instance of OUTLOOK otherwise it may not work

Hi Larkvale, thanks for your quick response

I'm adding here more information:
1) it is automatically disabled by Outlook (soft disabled), it changed from behavior 3 to 2 in the registry entry.
2) it is a com addin created with vs 2003 and vb.net
3) If I change the behavior to 3 and run outlook in safe mode , it is active, but still doesn't show the addin tabs (maybe in safe mode it didn't run it)..
4) I'm connecting right now to the client pc to execute r (addin installer and outlook ) as administrator

Larkvale, I found the solution.
The problem was that I didn't have installed the "2007 Microsoft Office System Update: Redistributable Primary Interop Assemblies", some interop was missing. I will check the setup.
