I could manage to get all extensions working on CS6, except for google search, which is not working and I wrote about it below.
It was installation order which is causing problem, here is solution just in case anybody has the same problem.
I disabled all the extensions and uninstalled free tools.
after installing it I installed following orders
I did not install html editor because it is not compatiable with cs6 as adobe took off a file the extension needs.
If there is still a link to the file please let me know.
Now for google search, it doesn't show any error but setting window is just blank (attached)
When I hit on on "inserch custom search", another window open (insert custom search and result) and nothing happen.
for DW 2014.1, I think free tool is not compatible since it was released before the 2014.1 and it is not updated.
(am I right?)
