I have a npapi plugin that run an exe on the client machine, now npapi is deprecated on chrome, so I'm trying to port my plugin to PPAPI.
Can I run an EXE from the PPAPI plugin?
Note: I only need this to run in windows.
No. See this post here: https://groups.google.com/forum/#!topic/native-client-discuss/1quAy0Y_xa4
This type of behavior is one of the major reasons npapi was deprecated, this capability is a huge security issue. If you don't need the exe to run silently, there are some methods there, however.
