How can I uninstall my office add in?

I developed an office add in and a setup application, but after I install it on my computer, and then I uninstall it, it seems everything is OK.

But when I want to reinstall it, I always get nothing. It seems there are some infor开发者_如何学Gomation retained in the registry. Is there any tools can help me to find them out and solve this problem ?

By the way, I used vsto | local to install my office add in. And I have completed all the added registry in my uninstaller, but seems not work

Rather than programmatically trying to uninstall, do it the old fashioned way. Remove the add-in via office, let it remove the keys and such, and then try again.

I believe an add-in is saved to:

• HKEY_CLASSES_ROOT\CLSID{guid}\addin-name\keys
• HKEY_CLASSES_ROOT\addinName
• HKEY_LOCAL_MACHINE\Software\Microsoft\Office\product\Addins\addinName (all users entry)
• HKEY_CURRENT_USER\Software\Microsoft\Office\product\Addins\addinName (current user entry)

and, depending on the system, the Wow6432Node as well under HKLM &/or HKCU

I've found that the click-once cache sometimes hangs on to these old versions and won't let you re-install. You can try a couple of things: 1) run the utility from MS called Mage. You want to run "Mage -cc" which clears the cache. 2) if that doesn't work you can add the environment variable: VSTO_SUPPRESSDISPLAYALERTS and set itto 0. Try the process again. This will give you a more detailed pop-up of information.
