I'm trying to install 64-bit drivers using DPInst.exe and Inno Setup. When I execute the installer, DPInst is launched and then displays the error "DPInst.exe does not execute on your current Operating System". This made me think that I grabbed the 32-bit version instead of the 64-bit version of DPInst.exe, but if I wait until the installer is done I can then run the DPInst manually and it executes just fine and installs the drivers.
Here is the relevant portion of my Inno Setup script:
[Files]
Source: "...DPInst.exe"; DestDir: {app}\Drivers; Flags: ignoreversion
[Run]
Filename: {app}\Drivers\DPInst.exe; WorkingDir: {app}\Drivers;
This seems pretty straightforward, so I don't know what I'm missing here. It works if I run it outside Inno Setup, so I'm not sure why I get an error about my current OS when it runs inside Inno Setup.
Any ideas?
UPDATE: Over the weekend, the machine performed a Windows update and Win 7 SP1 was installed. Now the DPInst when called from Inno Setup works. I then re-imaged the machine back to pre-SP1 and it again failed. I checked the DPINST.log and found this:

Notice the Version field goes from 6.1.7600 to 6.0.6000. The first run is from Inno Setup when it failed (notice ERROR) and the second run is when I run it manually. What does the "Version" field represent? And why would SP1 being installed make a difference?
Thanks,
Jason
