Install a 32-bit driver on 64-bit Windows

Yesterday a found out that my super cheap Chinese PCMCIA-SERIAL adapter didn't come with a driver for x64 based systems. The adapter uses a CH352 chip and the manufacturer of the chip ( doesn't even have any drivers on the website, let alone provide 64-bit versions.

Surprisingly, Microsoft had the answer this time.

You can install a driver not marked as 64-bit compatible if you create the following DWORD key in the registry and set the value to 1 (or anything but zero)


I didn't even have to restart the computer and it worked like a charm.

Of course, you do this and any other modification of the registry at your own risk. It is only recommended for testing purposes.
