patch to remove coinstaller from inf file

Description of problem:

W7 pvpanic.inf contains this block:
    [PVPanic_Device_CoInstaller_CopyFiles]
    WdfCoInstaller01009.dll
but does not contain that dll file. Installing a pvpanic device and attempting o use the driver results in a
    Windows encountered a proplem installing the driver software
    The system cannot find the file specified
error.

Version-Release number of selected component (if applicable):
0.1.105 (CD version)

How reproducible:
always

Steps to Reproduce:
1. Install a pvpanic device in VM
2. Attempt to update driver via CD

Actual results:
Driver install fails when it can't find file

Expected results:
Driver should install

Additional info:

Drivers are a bit out of my league, but I did try to research and make sure this wasn't an error of my own. If I am reading this link properly ( http://www.libusb.org/ticket/143#comment:6 ) then the dll isn't needed on Win7, as a higher version is already installed, and it would just be ignored, anyway.

I've removed the pertinent lines from the inf file, and it installs just fine--although I don't know if that means it's working or not. Patch for the inf file attached.

You can't remove these lines as they might break the driver's installation.

Which CD is missing the WdfCoInstaller01009.dll file?

The public -106 builds and later should have the .dlls in the right place. Closing, please reopen if issues persist.
