Running the application
Starting from version 7.1, you can run ONLYOFFICE Desktop Editors with the --ascdesktop-support-debug-info-keep flag. It can be used with the following values:
Parameters
| Value | Usage | Description | 
|---|---|---|
| 1 | --ascdesktop-support-debug-info-keep=1 | Runs the application. | 
| 0 | --ascdesktop-support-debug-info-keep=0 | Stops the application. | 
| default | --ascdesktop-support-debug-info-keep=default | The default application condition - the app is turned off. | 
To launch ONLYOFFICE Desktop Editors with this flag, use the same instructions as for the --ascdesktop-support-debug-info flag above. The only difference is that the --ascdesktop-support-debug-info-keep flag stores the value passed to it. You will not need to specify it every time you run the application.
