<p>I Have a problem with my custom Addin to word because sometimes, MS Word was disabled my addin, and I need to write another AddIn, which Was enabled to turn - on/off my first AddIn. Is it possible?</p>

<p>sorry for my English  :(</p>

What kind of add-in technology are you using? VSTO? 
What version of Office are you using?
In general it is possible to do what you want. However, the reason that Office disables add-ins is that the add-in threw an unhandled exception. In that case Office will set the
```
LoadBehavior
```
value in the Registry to 2.
Maybe it would be better to analyze and handle the underlying problem causing the exception.
