Fatal Error - Unhandled Exception

edited December 2019 in General ACT Discussion

Out of the blue - this started when attempting to load ACT

---------------------------Fatal Error - Unhandled Exception---------------------------
An unhandled exception has occurred.  ACT may close.Press Ctrl-C to copy this MessageBox.
System.ComponentModel.Win32Exception - The parameter is incorrect

  • Regardless of how it happened, the cause of the message is that the procMask line in the settings file references more CPU cores than your system currently has.

    For example:

    <Int64 Name="procMask" Value="255" />

    ...would mean that every logical core of a 8 thread CPU is allowed.

    I've never heard of this happening by mistake before, but regardless... my suggestion is to remove the line from ACT's settings file.
