This was quite an annoying error that wasted around 30 mins of my time today when i tried to connect my Nokia mobile to PC using CA-53 data cable. When i tried to connect the phone for the first time after updating PC suite, it gave me "Cannot install USB Phone parent" and "Fatal error during installation" error messages. A bit of Googling and i found out that the PC suite version i had installed at that time (6.86) was a little retarded and apparently the cable driver that came with it did not support CA-53.

Tried various suggestions on Nokia forums including removing all Nokia software in the system, cleaning registry and then installing version 7 of PC suite only to be greeted with the same error message. Here is what i did to get rid of this problem (It's pretty shorter than most methods mentioned; some of which even suggested using devcon to clean the system).

  1. Remove you mobile device from the PC if connected.
  2. Uninstall any older versions of PC suite and install the latest version. [Link]. Don't connect the phone just yet.
  3. Browse to C:\Windows\System32\Drivers folder.
  4. Locate the file WDF01000 and make a backup of it.
  5. Now delete WDF01000 from System32\Drivers folder.
  6. Launch PC suite and connect your phone. Installation should complete.

Good Luck!

    Thanks for sharing this help. It works now. Why cannot Nokia fix this. Their service was better year ago.

    Drinkuth the error is fixed in PC suite version 7 but it does not overwrite the buggy driver that came with 6.86 release, by default. Once you have installed version 7 and delete the driver file, setup re runs, this time installing the fixed driver which comes with pC suite 7.

    I'd really like to try this!! I've found the file, but my computer won't let me delete it :( A pop-up appears asking for administration rights (which I have), so I click 'continue' but it still won't let me delete the file or even rename it! (I'm able to delete other sys files in this folder, but not *this* file -- why??)

    There is a great tool Digeus I recommend to use it when there are problems with system. I also use Windows Tune Up Suite form Windsty. It repairs and optimizes the Windows.
