OK, installed and ran BD 2015 no problem last year, now when I try to uninstall/upgrade to 2016 I get an error that says I must manually uninstall BD 2011. Tried running all the old and new uninstall tools with no luck (but they did run successfully), regular AND safe mode. Why would 2015 install and work over 2011, but now I can't get 2016 installed? Running Window 10 now. Keeps tryin to install itself during boot_s, but fails with same error.
