I have now downloaded the Full Installer twice (on 2 different PCs), and neither one works!
On one PC, it gives an error dialogue: “Extracting error: SFX Header invalid”
On the other, it just does absolutely nothing at all.
Both PCs are WinXP-Pro + SP3.
In both cases, the download completed without error - but the 1st one is 370MB (388,600,000 bytes) and the 2nd is 409MB (429,100,000 bytes).
I used the download link given here: https://forum.sierrawireless.com/t/delivery-of-developer-studio-1-1-2/4454/1
