hello thanks for answer.
i run VS2010 as administrator.
However, a note: I uninstalling visual micro , clean de registry and apply the "devenv.exe /resetaddin Visual.Micro.Visual.Studio.Arduino.Helper". After this,� I see that the two menu bars arduino boards & serial communications are still here . Content is empty but they are there...

i've delete them manualy, they� were not populated...
after reinstall always same problem : one additionnal menu after each VS2010 start...
so no solution for me at this time...

With VM after 3 starts:


After uninstall VM :


After uninstall and "devenv.exe /resetaddin Visual.Micro.Visual.Studio.Arduino.Helper"


After right click in toolbar Arduino menus are presents

I applied the v25 : works fine  
Problem solved for me thanks !

I'm having this problem with v27. I don't get the additional toolbar items (I think you've prevented the duplicates being created), but launching VS2010 takes a long time on every startup.
My trace contains:

CreateCommandBarItemsPerm      Begin AddinVer=27

• VMDebugger (vmware), 
• Application Styling Configuration Dialog (Infragistics) - 2 instances or versions, only one is selected. Hm, that sounds suspicious.
• BuildVersionIncrement - disabled. I've had problems with it in the past

I cleared out a couple of other add-ins. Now it's just loading VisualMicro and the VMware one.  I still get the same messages in the vm trace file, but it doesn't sit there trying for ages.
VS2010 now loads at its regular pace + 2 seconds to cache Arduino libraries.  (VS2008 loads so much more quickly.. leaves me wondering which version to use for vm as I need both vs's on my machine anyway).

I have the same problem with loading. It takes forever to get started. I don't have the VM addin. Should there be some other thing to look for maybe?

bit more info...

1)
Explained: Moving to a vs extension might help purely because I think vs can be a bit unstable with addins. The addin system uses older OLE interfaces which microsoft seem to be keen to move away from.

2)
I recently found that vm was throwing an unhandled exception during startup. We never see it because vs protects against exceptions and does not show errors. However it is possible this contributes to the problem. I don't really know this for certain but it is fixed in the next release

3)
So far all reports of speed or startup issues have been solved by removing other providers addins or extensions. I have many microsoft extensions loaded in vs which do not cause a problem. It should not be possible for any extension or addin to interfere with visual micro but we have proven that they can.

So in the short term we should remove any unimportant 3rd party extensions and addins and look forward to vm moving to the extension system.
