I just tried updating to the new V2.0 of the companion software and…big surprise…it failed. It said that there was an error during file extraction. Here’s the trick to get around it and install it manually:
Go to here to get the newest pcsoftware.zip version:
http://updates.irexnet.com/companion/dr1000/
unzip it to a folder on your desktop or wherever else you want it. connect your DR1000 to your computer and make sure the companion software is closed out if you started it. Copy the contents of the unzipped pcsoftware.zip file to the folder on your DR1000:
D:\System\pc_application
(that’s assuming your DR1000 shows up as the D drive on your system.) Just replace any files that are older versions and you’re set! You don’t have to restart the device, just start up the companion software again by right-clicking on the iRexDR1000 in the windows explorer and selecting “iRexDR1000″. Your companion software starts up and it should say “V2.0″ at the top.
