Beyond Compare Windows Startup Crash - Elastic Endpoint Security

[Chris]

Beyond Compare 4.4.4 for Windows crashes on startup if Elastic Endpoint Security (https://www.elastic.co/security/endpoint-security) is installed.

The error dialog shows "An error occurred in the application."

Clicking Show bug report displays:
exception message : Assertion failure (C:\ContinuaCI_AgentWorkspace\Ws\11140\Source\Beyo ndCompare\Source\Vfs\VfsManagerImpl.pas, line 748).

I've submitted a ticket to Elastic support (#01170638), they are investigating.

Elastic support responded with a suggestion to add Beyond Compare to the trusted applications list.

The Elastic Endpoint Security startup crash appears to be fixed after I restarted my Windows 10 test system today. If you continue to have issues, please report them to Elastic support.
