Go back to the folder where you extracted the Togainu no Chi ISO, now go into the folder named "Step 2", then find the file named "TNC Image Patch", and run it.
Click on the "Next >" button, now click on the "Browse" button.
This is important! The image patcher doesn't know where Togainu no Chi was installed so we have to tell it ourselves.
If you followed my guide, Togainu no Chi should be installed directly to Drive C:. So find it through the new window that popped up.
Click on "My Computer" or "This PC", then find "Local Disk (C
".
Next, look for the Japanese folder named: 咎狗の血
And click OK.
Once the "Destination Folder" says, C:\咎狗の血 (Or wherever you installed TnC yourself) then you can click the "Install" button! ^^
Let it do it's thang.
When it's done, deselect any checkboxes that ask you to view any files, and then click "Finish".
