Windows 7 Connection Problem

[longhornss]

hello I am running windows 7. I have all the latest software installed and drivers updated. I am still having a connecting problem though my laptop chimes constantly when I connect to my VCM as if the interface USB is connecting and disconnecting on its own.

When it is not having this problem and is connected fine I get a multitude of errors/fails such as Bootloader download timed out, unable to locate VCM, Reading VCM Timed out, Requesting Access- Security Codes Denied.

Any thoughts.

I am running a bench top harness for my E40/T42

I get similar results with my 2000 Cavalier and 2007 GMC Sierra

There is only one car that I tune that I get this problem with. Everything else works fine.

Have you tried this?

Windows 7 64 bit operating systems driver install instructions
1)Download the drivers here http://www.hptuners.com/pub/HPT_MPVI_Drivers.zip
2)Unzip the drivers to your desktop
3)Connect your MPVI interface to your laptop
4)At this point the driver install will likely fail(it did for me)
5)Open the control panel and in the search window enter device drivers
6)Under Device manager select the update device drivers one
7)There will likely be two MPVI devices with an ! listed next to them in the 'other devices' section
8)Right click on the first one, click update driver software
9)A window will come up, tell it to browse my computer for driver software-from there find your desktop
10) it will now install properly
11)repeat for the second one and you're done!

Also are you running the 2.23 Beta?
