Hello all, after spending 2 days of discovering where my problem maybe is, yesterday solved all VM is now runing great in VS2010 Pro. The problem was in corupted installation of VS2010. Now I'm explain what I discovered, maybe this help to others who can't install VM to VS2010 Pro  For first I've installed VM at PC cca at february 2012 with Xp SP3, VM v.26, Arduino 1.0. There was no problem with install and functionality. In this friday I've installed VM to my PC with Win7 x64 HP, VM v.26, Arduino 1.0 and here comes the problem after installing VM. When I've started VS2010 Pro the error presented with some like this: <Visual Micro failed to create command bar items. Could not load assembly 'stdole, Version=7.0.3300.0'.......The system cannot find the file specified.> After many reinstallation of VM and reseting addin - no effect. Arduino Serial Port not showing and Tools>Arduino the same. What I've founded?

1. There is no difference between instal VM on WinXP or Win7.
2. VM v.26 is still stable and good.
3. Complet clear uninstall VS2010 (and all components like SQL Server,Office Tools,...) with RevoUninstaller (good aplication, enough free version, but Pro too). Some registry of VM we can delete manually.
4. Clear install of VS2010 (in programing languages for me C++ enough) and other of your choice.
5. After install VS2010 don't make upgrade, run VS2010 as Admin to take effect. Close VS2010.
6. Run Arduino 1.0 once and close.
7. Install VM.
8. Restart PC.
9. Run VS2010 as Admin, In Tools> set path to Arduino 1.0 and other options, then close VS2010.
10. Run VS2010 again as Admin, now maybe all ok, Tools>Arduino present, but Serial Port is detected due your HW config, I got HW Serial Port COM1 so this is presented. If not, close VS2010 and install driver (virtual COM) for Arduino HW boards.
11. In this situation I run VS2010 without Admin with no problem to work with Arduino.
12. Run Updates (VS2010 SP1 and other).

Thats all, wish good luck to solve this problem 

Hi,

with my old problem, there was this config:

VS2010 with SP1 and all updates today.

Then I've installed VM v26 and then I've recieved that error discribing in my previous post. The problem was in fact in corupted install of VS2010, don't know for what reason it was corrupted, but with presented solution everything work ok now  Thnx for great addin.

Great news no probl.
