Two different Advanced HMI apps cannot execute in same PC

[CarlosAguero]

Using the Advanced HMI solution, I created an application to communicate to a Control Logix PLC and send e-mails. It worked fine, no further issues.

Now, using again the Advance HMI solution (in a separated folder) I wrote a code to communicate to a Control Logix PLC and save data into a SQL server. I tested and it runs perfectly.

If I install 1 application in a PC it works perfect, but once I try to run the second application (in the same PC) it wont run. It will show only the first app I execute.

Has anybody from here experienced this same issue?.. what am I missing in the configuration?..

I'm using Visual Studio Community 2017.

Regards!

Thank you Archie, I already did what they mention and still having the same issue.
I selected Multiple startup project in the solutions properties.

any other recommendations?...

If removing the check from the Make Single Instance Application did not work, I'm not aware of any other things that would cause this.

From the screen shot it looks like Carlos is on the properties page for the solution, not the project.

Right-Click on the Project, not the solution, and you should het a screen that look something like the attached.
Un-check the 'Make Single Instance Application.

You'll need to do this for both applications.

Also, my screen shot os from VS2015, not sure if it'll be different in 2017.
