1. I haven't tried your syntax from above, but I'd rather use
or under Windows in a safer way::

2. Maybe you forgot to set the Repository active via setRepositories()?

3. Why don't you just set the repositories at startup, e.g. in 
Rprofile.site or your personal .Rprofile via:

       r <- getOption("repos")
       r["myCRAN"] <- "file:////store/ligges/public_html/CRAN"

works for me with store being a machine in the network (via UNC path).
