The extension manager and all my adobe application are the latest version,
First time it says failed to initialize, after that, it can complete the initialize yet find nothing in it.
I tried to unistall and install the app again & again & again... still not working.
Kind of solve the problem.
I installed an old version (7.2.0) , finally find my products, then update to the latest version.
Although it still have initialize problem and can't find DW, but PS extension can work properly.
