There might be something in the system Event Viewer, depending on the cause.
A couple of things you can try:
Built-in diagnostic:
- Edit 2024: Instructions here got garbled over the years by forum changes. See this more recent thread instead: Dopus 13 not running after install - #4 by Leo
Process Monitor:
If that doesn't work, it's likely something low-level is killing the process very early on.
Using Microsoft ProcessMonitor to monitor which files and registry settings are accessed when the process tries to start may point to where the problem is.
You can save and zip process monitor logs for us to look at via the program's File menu.[/li][/ul]
If the problem is something like anti-virus killing the process because it's new (please don't discount this possibility, it happens a lot with new versions of software and some antivirus tools) or a system issue then it's possible dopus.exe is being killed before control is passed to any of our code, in which case the above tests may not show any output from dopus.exe.
