Running EXE with parameters from Acumatica

There’s a difference between having the browser open the executable from Acumatica webpage and having Acumatica server run the application (without using the browser, without direct user intervention).

It is quite easy to open an external application from the browser. You just need to associate a file type with an application in windows (example: docx files opened by Word application, .xlsx files opened by Excel..): Change default programs in Windows 10 (microsoft.com)

In Acumatica webpage you can throw a file redirection exception to open the app.

It is also possible to launch an external app with a custom URI scheme handler.

This is the method used for url like ‘mailto:email@address.com’ that opens a windows email client:
windows - URI scheme launching - Stack Overflow

It is a very different scenario to have Acumatica server application directly execute a remote executable located on a different network. Acumatica server application runs on ASP platform and ASP doesn’t allow such remote code execution. That would be a major security concern if it were possible. If you need to communicate directly from Acumatica server application to a remote network we recommend to build an external web service that can be called from Acumatica.
