Answer 1

You might have some problem in your Local Settings folder. Try deleting it, reboot and it will be recreated. That's how I've solved a few access denied errors when dealing with QlickOnce.
The Local Settings-folder is hidden default. It's found here on Windows 7 (and Vista):
C:\Users\{user name}\AppData\Local
And here on Windows XP:
C:\Documents and Settings\{user name}\AppData\Local

I got the same issue on one of my team mate's machine after installing setup of word addin. I created installer using Installshield's limited edition. The issue was in registry entry. Path in Manifest entry was having "file:///" at start which was somehow causing error.
First I manually changed path in manifest registry (at HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\Word\Addins\YourAddin\Manifest) from "file:///C:/Program Files (x86)/...../My.vsto" to "C:/Program Files (x86)/...../My.vsto" and it worked. Then I fixed that in my setup project too.
Hope this helps somene.
