I did a very quick little update this morning (same download URL as previously):
1 - Tooltip on VST menu (eg. SONAR Cakewalk VST) now shows last scan time for that VST inventory. I'm pretty certain I've calculated it correctly from the value the VST scanner stores in the registry, but I was seeing some scans reported as being done in 415AD so I'm not 100% sure :-)
2 - VST scan paths now splits user and internal paths
3 - VST scan paths popup includes a checkbox alongside each path which is checked if the path is valid (ie. it helps detect incorrect paths)
4 - VST list and properties window shows an icon (plug with a red minus) if the dll doesn't exist - another debugging tool
