I wanted to post an update on the issue surrounding this bug. Basically, the compiler build server was writing the final compiler product to an "F:" drive. Due to a bug in GCC itself (http://gcc.gnu.org/bugzilla/show_bug.cgi?id=46501, among other reports), the references to "F:" from the build server were leaking into the final compiler products.
Normally the reference to F: wouldn't be a problem because most Windows machines won't have a permanent entry for this drive unless it was permanently connected. However, if Windows disk management has somehow decided to permanently assign a certain removable device the "F:" identifier and the device isn't connected, the user will see this cryptic message reported by the original author.
To fix the issue, we've moved the final build location on the server to the "C:" drive, which almost every Windows machine will have present. The fixed version will appear with Simply Fortran 1.30, which is slowly moving towards release.
