It can be run under the electron, development environment under the win7 system, but the flash failed to load in the production environment after packaging to generate asar. What may be the problem?

electron, under win7 system I use app.getPath ("pepperFlashSystemPlugin") development environment to run flash, package to generate asar or flash load failure in production environment, what may be the problem? The second question is that I use relative position to get flash, whether it is a development environment or a production environment, flash loading failure, whether I missed anything, thank you.
