Process Monitor is a free tool that allows you to troubleshoot file/folder and registry key access problems that might be causing your application to behave unexpectedly.
In order to monitor file events, registry events, and process and thread events generated by an application using Process Monitor, follow the steps listed below:
1. Download Process Monitor from the following website:
2. Launch Procmon64.exe.
3. If you are prompted with a filter dialogue, dismiss it for now.
4. Deselect the Capture button to stop logging as shown in the screenshot below. Alternatively, click File > Capture Events or use the Ctrl+E shortcut.
5. Click the eraser to clear all current entries. Alternatively, click Edit > Clear Display or use the Ctrl+X shortcut.
6. If you intend to capture all program activity, press the Capture button again whenever you're ready and then skip to Step 11.
IMPORTANT NOTE: To troubleshoot your executable, especially when it interacts with other applications and you are not sure which application might be interfering with yours (e. g. AntiVirus), do not set a filter and skip to Step 11. Close unrelated programs and processes running on your computer to keep the log as small as possible.
If you only want to capture MATLAB activity, follow the steps below to set up a filter to do so.
7. Click the Filter funnel button, or click Filter > Filter.
8. In the drop-down menu reading "Architecture", click it and change it to "Process Name".
9. In the text field to the right of "Process Name" and "is", type in the exact name of your executable, including the extension (.exe), for example, "matlab.exe", and then press "Add".
10. Press OK when finished.
11. Press the capture button again. Alternatively, check File > Capture Events or use the Ctrl+E shortcut.
12. Start MATLAB.
13. When finished logging, stop the capture, and click the Save button (floppy disk).
14. Save the file with the default settings (PML format) and remember the path where the log file is saved.
You will likely need to have this file compressed into a ZIP archive to be retrievable.
