I'm sorry, that was my local system failure. After the next windows update my system fell down into unbootable state, it's boot recovery system was used automatically and a previous system state was restored. I have a precious run of Total Network Inventory 1.6.7.2750 under my 32-bit version of Windows 7 Enterprise after the reboot. Neither reinstall was needed again nor options reset. I'm still wondering what was happened.
Thank you for your answer.
