Issue
In older versions of Vista (<5.1.5), LMTools version 11.4 is used, and seems to crash sometimes when using the diagnostics functions.
Environment
Vista 5.1.4 and older
Cause
Unstable software
Resolution
Upgrade LMGRD.exe and LMTools.exe by replacing them with files of version 11.6 that can be found in TAC Vista versions 5.1.5 and later.
