A: Yes, 100% free. Trend Micro provides it to all users—even those on a trial version. You do not need an active subscription to download or run diagnostics, though repairs may require a valid license. Q2: Why does my antivirus flag the toolkit as a risk? A: Some third-party AVs (like Windows Defender, ironically) temporarily flag TMDiagToolkit.exe as "potentially unwanted" because it uninstalls security products. This is a false positive. As long as you have the verified digital signature, add it to your exclusions list. Q3: Can I use this toolkit on Mac or Android? A: No. The Diagnostic Toolkit is Windows-only. For Mac, Trend Micro offers a separate "Removal Tool" (not the Diagnostic Toolkit). Do not try to run the .exe on a Mac using Wine—it will cause kernel panics. Q4: How often is the toolkit updated? A: Trend Micro updates the toolkit approximately once per quarter (January, April, July, October). Always re-download the verified version before a major repair to ensure compatibility with the latest Windows updates. Q5: I clicked "Download" but nothing happens. A: Clear your browser cache. Alternatively, use curl or wget from Command Prompt (admin): curl -O https://files.trendmicro.com/products/tsc/diag/TMDiagToolkit.exe Then verify the signature manually.
