The web server config tool is blank, and I can't add anything, warning box says supported versions are 4, 5, 6, and 7x. V8 installed. I have googled this warning message but still haven't found anything helpful.
There are no handlers that I see for CF related file extensions.
thanks!
Are you, by chance, using an old installer package?
CF10 support for Win2012 and IIS8 was added around March of this year. I wonder if you're using an older installer that isn't properly taking ths into account.
Try downloading CF10 Developer from Adobe (choose x86 or x64 as applicable) and see if using that installer works for you (If you have a license, you can pop it into the CF Admin after install and unlock it to Standard/Enterprise).
