C # detect Framework installation when the application is running

Because the program runs in a Ukey (USB flash drive) instead of a Setup package, you cannot directly run the. net exe startup program if the Framework is not installed at startup,

Solution:

Startup.exe written by cup.exe is used as the startup program. It also checks whether the Framework is installed on the local machine. If not, c ++ calls start installation. After the Framework is installed, it starts the C # application.

Among them, the C ++ detection and installation startup program code is as follows: VC ++ 6.0 implements a hidden form:
