Can say the detailed point? If I use the green version of the 7 z, and then manually add in the path environment variable, using the registry to find relevant information can also find right?

CodePudding user response:

1, if through the installation, what information is 7 z in registries?
2, if you know the relevant information, you can determine whether to install
3, if it is a green version, so you may want to write a REG alone to register to the corresponding registry node
