ASHGPS: 11 November 2010: MobileMapper Office for MM6 & MM100 220.127.116.11
In the last message, there were links to "Mobile Mapper Office for MM6 and MM100" which were valid links, however the installation files were not complete.
A new file has been uploaded to the Ashtech FTP site, I have tested it and it installs without issue (even on Win 7 64-bit). Here is a direct link:
Hopefully you will find the new installation works without issue, let me know if you have any problems.
