When try to uses flash player in China, it will give me a hint "This Flash Player is not compatible with your region, please reinstall Adobe Flash Player", while we all know this is a fake message, there must be some kind of policy limitations for it.
Maybe it's a restriction put by Adobe and Not Microsoft. I'm well aware that Adobe, due to U.S sanctions on some countries, have restricted download/usage of their products.
plus, Flash player is Dead!. and it's going to be depreciated Very soon in the chromium engine, that means No more support for it.
The BEST option for you is to stick to a browser like google chrome if you really need to use flash in this little time that it's available. the new Microsoft Edge and the dev team shouldn't spend time on a technology FULL of security vulnerability and a technology that is going to be depreciated soon. by the time the new Edge reaches its stable release, there won't be ANY support in the chromium engine at all. so better drop the support for flash right now.
