Which part isn't working?
The SDK needs to be installed on the computer. The directions i posted are if you didn't rename it and you have in the C:\ directory, without it being in any folder.
If you haven't already, go to:
Android Developers
and download the sdk, unzip it and cut/paste it to the sdk directory.
Next, Install the Java JDK 32-bit
Next, Install the latest version of HTC Sync, this installs the proper drivers, but don't run the program.
fire up command prompt and try it again.
