Just a quick hint: if you're installing addins for Visual Studio and the installer quits with a "Could not access network location "\\SomePath\Visual Studio\Addins", this probably means your "My Documents" folder is stored on a network drive, causing the installer to fail (for some reason I haven't yet discovered).

I found a pretty quick workaround, which is temporarily changing the location of the "My Documents" folder to a path on a local drive. You can do this by changing the registry key (all usual disclaimers apply, I didn't touch your computer so I didn't break it) "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurentVersion\Explorer\User Shell Folders\Personal". Note that the installer won't actually use this path to store anything, so it's safe to use any path you deem fit. If the addin installed properly after this hack, don't forget to change the registry key back to its original value and you should be fine.

I haven't tried it for other similar issues, but it might even work with any other type of software that breaks with the same error message.
