I use your V-ray tools, and I started having Vray launch upon starting SketchUp even when it was disabled. (This issue started since SketchUp 2016 Update). I need it disabled until I launch Vray from your extension (This was the purpose of that extension, I am sure you understand what I mean) There is launch order for signed and un-signed extensions according to help page. Which I think is the cause of the issue.
