Known Issue: Usage .mmi files may fail to import if any software names end with a digit or special character and contain a "\" after the last space (IOJ-2181551)

Known Issue: Usage .mmi files may fail to import if any software names end with a digit or special character and contain a "\" after the last space (IOJ-2181551)


Usage data gathered by the FlexNet inventory agent may fail to be recorded in the inventory database and reported in FlexNet Manager Suite if the application package name associated with any metered executable matches both the following conditions:

  • The application package name ends with a digit or one of the following special characters: ()[]._
  • A backslash character ( \ ) appears in the application package name after the last space (if any)

A potential symptom of this issue is that new usage files regularly appear under the C:\ProgramData\Flexera Software\Compliance\Incoming\UsageData\BadLogs directory on the inventory server (FlexNet Manager Suite On-premises edition only).


An example of data usage data appearing in a usage .mmi file generated and uploaded by the agent that will cause this problem is:

<APPUSAGE NAME="Hardcopy (C:\Program Files (x86)\Hardcopy)"  [...]/>

An attempt to process such a .mmi file with the mgsimport.exe tool fails with an error like the following:

Processing file C:\ProgramData\Flexera Software\Incoming\UsageData\dsk123456 at 20210323T000002.mmi.gz:
