Kerkythea Won't Open Automatically

I've just install SU plugin exporter to Kerkythea but ot this message and answering Export Options


"Model and light save in [...]etc
open exported model in kerkythea?"

I click yes and then comes:
"a file :'C:\Program files (x86)\Kerkythea Rendering System\start.kst'
could not be created.
PLease change permissions for folder\files.
Kerkythea won't open automatically"

How should I deal with this? I've read a similar problem as this but the solution and the what the guy did to solve the problem didnt work in my case. Can you please help.

Thanks Iwan for taking time to put the screenshots! Exactly what I've been looking for.

I know I am way late but wanted to thank to Iwan for screenshots which helped me too! I ran into the same problem and when I found this post - it works!

Thank you very much, Iwan. I'm very new to SketchUp and Kerkythea and encountered this problem. If not for the screen shots you posted, I'd have wasted a lot of time reading through various forums.
