I have created the VB.Net program and I have added encryption to the connection string which is stored on app.config file, after adding this code runs smoothly as expected on my system. but it doesn’t launch in the client system. I have already installed the .Net run time plugin.

Note: Code runs without encryption code on the client system.
anyone can help me where I am missing.

I tried disabling the antivirus, doesn’t worked for me.
