My company has my home directory on a network share. When I install NPanday 1.4-incubating from the msi, I get the following:
Failed to open XML file \\[network_share_name]\Home$[username]\Visual Studio 2010\Addins\NPanday.VisualStudio.Addin, system error: -2147024891
It seems to be a permissions issue on the network share. When I run the installer under an account that has a local HD home folder, it works fine.
