I have an addin developed using VC++. I am planning to create an agent that
is going to check for updates and do an automatic update of this addin. The
question I have is: can the automatic update be done without closing outlook?
If Outlook is open when the agent tries to update, what can I do? Has anyone
else done it and please share the idea with me?

The main idea is that the update has to be completely automatic without any
user intervention and I can't use ClickOnce or the new VSTO technologies.

Thanks
