Error 'Application is already running'

An error occurred during platform initialization: Exception has been thrown by the target of an invocation
This error occurs due to the removal of the file by the Avast antivirus or AVG antivirus, which is necessary for the correct work of the platform.
Our developers informed Avast and AVG companies that the file CefSharp.BrowserSubprocess.exe is a part of the CefSharp library — HTML5, JavaScript and PDF supported Web browser based on Chromium Embedded Framework. It allows using web browsing services in applications to create the user interface. We use this library in our platform as well. More information about it you can read here https://cefsharp.github.io
We don't know a reason why antivirus sometimes recognizes this file as suspicious, but if you search in google, you can see that there are already many reports from users about the same problem: https://www.google.com/search?q=cefsharp.browsersubprocess.exe+antivirus In general case antivirus developers recommend reporting a problem as false positive.
To be 100% sure, that this file is not dangerous, you can check it manually using different web services like https://www.virustotal.com They will display your results received from different antiviruses.
As a solution, we recommend you remove Avast or AVG antivirus (completely) and reinstall the platform.
