Error Message "Application cannot be started. Contact the application vendor." for Visual Studio Windows Forms Application Deployment.

Question

Hello,

I am getting this error when trying to launch a ClickOnce app. I tried troubleshooting and searching for answers online but didn't seem to find anything helpful that would resolve this issue.

This is happening on every other machine except the machine the application was created on (mine).

I have provided the log file below for your reference and would appreciate any insight/ help possible.

Sincerely,
Joe.
