Path not found by DPInst

Question

I'm installing a driver using WiX with DPInst, as per this tutorial. It works fine on Windows 7, but I'm trying it on Windows XP, and I get an error dialog popping up saying:

ERROR: Path 'C:\Program Files\My Driver\package\driver.inf' not found

after which it prints a long usage message.

If I navigate to C:\Program Files\My Driver\package\driver.inf before I close the dialog, the file is there, at that location. In the InstallExecuteSequence, InstallDriver is set to happen Before InstallServices. What's going wrong?

Note: I've tried running DPInst from the command line, and I get the same error.

Also, I've tried moving DPInst into the same directory as the .inf and tried running it without the /PATH argument. Strangely, I still get the same error (that is, it gives the exact path to the .inf that it "can't find". This is very strange indeed.

I think that when you want to install a driver using DPInst.exe with /path you should only provide the path to the directory that contains the .inf file. That is: dpinst.exe /path "C:\Program Files\My Driver\package\".
