"Unable to start process lpstart.exe. Start process injected lpstart.exe failed
We are encountering an issue when attempting to launch an application via Pega Robot Studio (version 22.1.49). The process fails with the error: "Unable to start processlpstart.exe.. Start process injectedlpstart.exe failed." However, the application launches successfully when executed manually.
Our environment includes Pega Native Foundation version Proprietary information hidden2 and .NET Framework 4.8. Despite this configuration, the application fails to trigger during interrogation as well, resulting in the same error.

@JoelPrakashJ2907Your version of Pega Native Foundation was hidden by the website. You might need to post it in separate lines as shown below;

The version I listed above is the one that shipped with the 49 build of 22 that you are using. You might try using the latest PNF to see if that resolves your issue. You can acquire that by downloading the latest Runtime version and locating the installer from inside the zip file. You do not need to install a newer version of Runtime to update PNF. The latest version of PNF is;

Are you certain that is the executable the application that you need to interrogate is using? If not, I would check using Task Manager to make sure. Launch the application and then locate the application in Task Manager. Right-click it and select "Go to details" to locate the exe it is using. You might check that this application is entirely closed before you start interrogation. If it still isn't working, make sure it is closed again and before launching change your StartMethod to MonitorAll and then start interrogation. After you see the interrogation form, start the application. Let me know if those work.
