1. Use Windows Explorer, not Internet Explorer.
2. Right click on the file where you have saved it. One menu option will be 'rename'. Select that and rename the file support_asr.dat
3. Connect your unit to the computer but do NOT start Home.
4. Again, using Explorer, highlight the (renamed) file and right click for the 'copy' option. Select that.
5. Use Explorer to highlight the asr folder on the unit. Right click the folder and select 'paste'.
If you see a screen asking you to overwrite an existing support_asr.dat file, then all this was for nothing as you do have the file in that folder.
