Application crash when hitting the Save button!

Using the release version 2.2.155 of Carnac under Windows 10:

As soon as the Save button is hit, the software dies.

It is better to have app crash report

I installed now the version from http://carnackeys.com with file Carnac.application - and here no problems with saving. It is only the release 2.2.155 from the github site.

You might find some in the Event Viewer about the underlying error:

• the log you want is Windows Logs | Application log
• set the Filter in the right-hand column to Error

It turns out for me that the Carnac need escalated access and denied by system, thus crashes.

Thanks @shiftkey for the EventViewer tip. I found below and use the workaround to run the program as administrator. Save the config with no crash.

Application: Carnac.exe Framework Version: v4.0.30319 Description: The process was terminated due to an unhandled exception. Exception Info: System.UnauthorizedAccessException at System.IO.__Error.WinIOError(Int32, System.String) at System.IO.FileStream.Init(System.String, System.IO.FileMode, System.IO.FileAccess, Int32, Boolean, System.IO.FileShare, Int32, System.IO.FileOptions, SECURITY_ATTRIBUTES, System.String, Boolean, Boolean, Boolean)

Good thing is, I do not need the admin right to use it. only when I want to modify config should I use administrator to run it.
