With logging enabled, perClass Mira will store information about its internal processes in a mira.log text file. This may help us to understand and fix issues.


In order to enable logging:

  • Close any running instances of perClass Mira.
  • Open the mira.ini file located in C:\Users\USERNAME\AppData\Roaming\perClassBV
  • Enable logging by setting: logMessagesToFile=true
  • Start a new perClass Mira instance, the Output window will now show in yellow that logging is enabled.


The log is stored in a mira.log file in the same directory as above.


TIP: You may quickly open the license directory by Help / Open license directory command. However, please note that when any instance of perClass Mira closes, it saves its settings back to the mira.ini file overwriting its content. Therefore, you may lose settings edited externally. That is why we advise to close all instances before editing the file.


TIP: Disable logging when not needed. Keeping it enabled will incur a performance penalty, specifically when acquiring from a camera.
