Visual Studio 2005 Addin install over network


I am having trouble in installing the SubSonic tools where the home path is on a network drive. The error given when I run the .msi is "could not access network location \servername\dir\VisualStudio 2005\Addins".
I have found the following previous issue related to my problem.
I'm using VS 2k5 Professional, I've downloaded the current source, took off the source control and the SubSonic Tools does not compile so I can do a manual add of the SubSonic Tools.
Though I have found an issue related to my situation, I would ask / request / beg for some solution to be created or noted.
Thanks ahead of time for any help.
