Kindle Fire HD - Win 7 Driver Install Fails - MTP Driver Error

[phunzoid]

i recently purchased a Kindle Fire HD 7" (tablet), and i have 2 PCs running Win 7 Ultimate x64 w/SP1...on the one PC, when i connected the Kindle via USB, Windows recognized the Kindle as a USB mass storage device as it should , installed the drivers, and i was able to access the Kindle via Windows Explorer to transfer media

but on the second PC, when i connected the Kindle via USB, Windows recognized a new device, but the driver install FAILED, and i got an error message stating "MTP" Driver could not be installed...i tried this several times, and always the failed driver install....i even did a fresh install of Win7 x64 on to a brand new HDD, and i got the same error again ...so obviously the Kindle does not show up in Windows Explorer, and i can't transfer anything to/from it

in Device Manager, under "Other Devices", i have "MTP" listed with the yellow triangle...i have tried letting Windows update the driver, but it always comes back with unable to locate a driver

i've contacted Amazon, but they're clueless, and believe it's a Windows issue...i've searched everywhere online, and it seems i shouldn't need any special drivers with Win7, and that Win 7 should install the device automatically as a "mass storage device"...and as i mentioned, on one of my PCs, the install worked fine, it's the second PC that is driving me nuts

what can possibly be the problem?

Have you used other usb devices on this computer? like pendrives datacards etc. see if they work fine or not.

Fixed

I found the fix for this by accident. I was trying to start the Diagnostic Policy Service as it would not run. It gave me 1079 error. I found the fix online by changing the login to local service instead of local system. As soon as I changed them and started all three Diagnostic services the IPhone and the Kindle both popped up as external drives on my computer. The Kindle still had an error and I went to Device Manager updated the drivers and both are now connected and working. Thanks for all your help.
