Came in here looking to make a post of my own and stumbled across yours instead. I'm having the exact same issue you're having except I'm on a Windows 7 x64 machine. I see you've gotten no kinda help up in here so I'm gonna email Cobly about this and see if he has any advice for resolving this issue. It's got to be something related to newer FTDI drivers because I've never had an issue with my 1.3 cable in the past. I've tested this on two different machines but keep getting the same error on both.
Here are some screenshots I took of the error when trying to use the drivers from EcuFlash v1.44.4361 that hopefully might be of help.

So basically...
- I uninstalled all the current drivers from the system.
- Go into Control Panel > Programs and Features and make sure to uninstall BOTH Tractrix Drivers towards the bottom of the list.
- Also with your cable plugged in, go into "Device Manager > Ports" and right-click on anything in there that says "OpenPort" or "USB Serial Port" etc. Then select "Uninstall" and make sure you check the box that says "Delete the driver software for this device".
- Then under "Universal Serial Bus controllers" look for "OpenPort 1.3 Subaru" and right-click and Uninstall that as well making sure to check the box that says "Delete the driver software for this device".
- Then I ran "DPInst.exe" from the "drivers\openport 1.3\" folder. EcuFlash v1.44.3721
- Then after everything installed without any errors I ran "DPInst.exe" from the "drivers\openport 1.3\" folder. EcuFlash v1.44.4361
I noticed that it might be best leave the Tactrix cable plugged in while doing all this. There were a few times during testing that I didn't have the cable plugged in before I ran DPInst.exe and then I plugged it in afterwards and I still got the error message, even with the drivers from v1.44.3721. So make sure that you try it with the cable plugged in if you're still having issues.
