I have found a solution for the error 0x80040707 that appears when we try to install trackir software.
I have Windows 7 64 bits but no problem if you have an other one. That would be the same solution.
Software version: 5.1.3
Hardware: Trackir 5
These are the steps:
1. Install software in other pc (what??? other PC?? yes, in other PC).
2. Copy the folder "NaturalPoint" installed in "your other PC" (by default in
C:\Program Files (x86)\NaturalPoint, with Windows 7) to your main PC. Copy this folder where you want, but would be better to do this into here: C:\Program Files (x86)\
3. Connect your Trackir hardware. Windows will not find a driver but don�t worry, we do it manually.
4. Go to "devices admin",
right clic over your "unknown device",
then "propieties",
now "Hardware" tab,
"controller or driver" tab (sorry, I'm from Spain and I have a spanish version. I don't kown how is that in the english version)
"update controller or update driver" button (sorry, the same before)
"search software manually"
and finally search C:\Program Files (x86)\NaturalPoint\TrackIR5\Drivers
That's all and works fine.
Sorry if I was not clear.
PD: I'll send you the invoice next week,
