Vista64 business MPVI drivers...

[Keith@HPTuners]

You'd still need to use our .inf files which will break digital signing.

When is there going to be a digitally signed driver for HPTuner?

[Keith@HPTuners]

Its on our todo list but I'm not sure when we'll be able to get to that.

Any update on Signed Drivers? I know its the holidays and all, but is it atleast on a roadmap somewhere?

Yes Please. I can NOT get it to work at all on new box

I just went through this with my new vista laptop.
Go to www.ftdichip.com/drivers/d2xx.htm
In the comments next to the second driver down (2.04.06) there is a hot link "setup executable" download that and run it on your computer. After that hptuners should install with no problem. That is what fixed it for me.

Hmm. I just use unsigned (not WHQL anyway) drivers and said screw it (just installed vista 64 for the first time cause I upgraded to 4gb of ram).. They seem to work fine.

What about Windows7 ??

It has the same issue with unsigned drivers ?? I'm running the beta and getting it refusing to load....I'm going to try this workaround posted above, but looks like HP is going to have to release one soon for when the next Windows ships

Just puchased a new Dell Inspiron with Vista. I have tried all of the posted remedies and still cannot make it work. I have verified the HP Tuners MPVI channel A & B are installed and the driver alterations recommended in the forum also completed. The message I receive is: "The interface was not found or is not responding. Verify it is connected properly and that the vehicles diagnostic port has power."
Ignition is on and power light on the tuner is on; Anyone have any suggestions, thanks for any assistance.

Gilbedr did you try the f8 thing. Also do you have windows 64bit or windows 32bit?

[Gilbedr]

I have spent at least sixty hours trying every suggestion found in this forum (and I appreciate all the help suggested), however tolerance has given way (my wife is complaining about the number of times I have used the "MF" comment). I requested Best Buy to load XP but they declined, so this afternoon I dropped it off at a computor specialty shop to have XP installed. I am hoping this resolves the problem.

Brandon, I tried that, but I'm still getting a Code 39.

Here's my error:
