At the restart of Excel, in the DATA bar, I can't see the Icon of MySql. 
I've check in the registry and in option->add-on menu in Excel, the add on is there... If I try to load it.. (from the menu on the bottom) the popup window show to me the plug in I try to check the box and confirm... But nothing happen.. 
Of course I've on the same machine installed the MySql server. 

Environment: 
Office 2007
MySql server 5.6

Reaaly no idea. Isn't the fist time I install that. And always work.

You do not have access to bug #70994.

Can you please share more details about the installation?
I could not reproduce the problem following the steps you described.
Some details that would be helpful:

Office version and bitness.
VSTO version and bitness.
Windows version and bitness.
Windows registry path where MySQL for Excel got installed.
Windows registry path where VSTO got installed.
User that installed it was an administrator?
Was the MySQL for Excel a new installation or an upgrade from a previous version?

Thanks.

Still I don't understand why I cant access to this link..

Some information more. 
All the time I launch Excel, the key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Excel\Addins\MySQLForExcel\LoadBehavior 

is set from 3 or 2, as I write, to zero. 

I've check the antivirus status (disabled)

I've see also i don't have the Addins in

HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Excel

that is normal ? 

I'm running as administrator. 

If I go on Excel on the Add in menu, I see my add in there, I choose add in COM, and I launch that, I see the add on available, unchecked. In the lower side of the dialog box, I see the behavior at start up: not loaded. 

if I check the box and I press "OK" nothing happen. 

Really frustrated. 

Thanks for any help

It is correct the add-in is not installed under the HKEY_CURRENT_USER registry node, it must be installed under the HKEY_LOCAL_MACHINE one for the add-in to be accessible by all users.

I found the reason of your problems, will add another comment with all that information.

The problem is caused by a reported issue with Office 2007 and COM Add-Ins, a Hotfix from Microsoft is needed, that hotfix is installed also by Windows Update so if you are seeing the issue it means your computer does not have all updates from Microsoft applied.

After the updates are installed or the hotfix is applied the Add-In works fine.

Here is the Microsoft article that explains what I mentioned above:
