I have succeeded in getting Cosmos/M 2.85 to run on my XP 64 machine. Here are the areas of difficulty in the order in which they need to be solved:
1. Parallel port
2. Sentinel/Rainbow license server
3. Software Installation
Parallel Port
1. Newer machines don't have parallel ports so a PCI/e or PCI card needs to be installed and gotten to work
2. 3rd party parallel ports can be tricky to get working. In my case with a 64 bit Phenom motherboard and an Oxford parallel port a manual install of the port was required.
3. You might need to have a parallel port printer handy to check the port function before you install the dongle.
4. Frequently the port with a PCI install will be named LPT3. Using device manager make it LPT1 just for consitency.
5. Once the parallel port is working install the dongle
Rainbow Sentinel License Server
1. Google Rainbow Sentinel Support for the SuperPro dongle
2. Download the latest driver and SuperPro Medic
3. SSDCleanup is also helpful if you need to uninstall previous drivers
4. Install the Sentinel Protection Server
5. Install SuperproMedic and check that the driver and dongle are visible and working
6. Fix problems if they occur
Install Cosmos/M
1. Install in the usual way. It should install as a 32 bit app
2. Use the license administration tool to check that your license is working as intended

Your mileage may vary. This is what worked for me. If you find something different works for you then please post in forum and I'll update the FAQ.
