When installed on my Win8.1 system, I get the warning "Dashboard is not fully supported in Windows 8. Some operations will not be supported." On my W8.1 desktop I lost "Life Remaining & Temperature" on the Status page, and "SMART - Advanced Details" on the Tools page. Similar function loss on my Win7 system. So... if you can do without the warning & SMART long test completion on SOME F/W revisions, and I can... go back to earlier Dashboard versions, and I did. My best results: Win8.1 - use v 22.214.171.124, Win7 - use v 126.96.36.199 Added info: To "regress" rather than "update," I first un-installed v 188.8.131.52, then deleted the program's Dashboard folder with >200MB of stuff not removed by the un-installer before re-installing older versions.
