What I have found is you need to set the "Hayabusa ECUeditor for K2-K7 models" program to "Run as administrator". Because it's not like other std programs you can't just find the .exe file in a folder and right click and then click "Run as administrator" like you will for the Flashing software. You have to go through a few different steps.
1st) Go to the file "Hayabusa ECUeditor for K2-K7 models" and open the file the normal way you would do it.
2nd) Once you have it running hold down the keys "Crtl and Alt and Delete" then let go and Vista will pull up a screen giving you a few options. You want to click on "Start Task Manager".
3rd) The Start Task Manager program opens and usually it will have "Applications" showing 1st that are currently running. You should see "Hayabusa ECU......." under Task. Just to the right of "Applications" tab is a Tab called "Processes" click on that. This will show you all the .exe files. You will find "Hayabusa ECUeditor.exe" there. Right click on "Hayabusa ECUeditor" and click on "Properties"
4th) When the "Properties" window opens click on the tab "Compatibility" and down at the bottom left you will see a Box you can click for "Run this program as an administrator" click on the box so it has a check mark and then just click the OK button.
Now you have done all that just close the "Windows Task Manager" window. Close your "Hayabusa ECUeditor......." program and then restart your "HayabusaECUeditor......." again but this time it should have a "User account control" window pop up, just click "Allow" and now your program should be up and running properly.
