Sorry that you're running into trouble with our product. Just to confirm, could you let us know the following first: - Main reason for running Trend Micro Diagnostic Tool and features you're trying to run - Were you able to open Trend Micro Diagnostic Tool at all?
Please provide a bit more info so we can understand more background before recommending a solution. If you can provide some screenshots, that'd also help us troubleshoot more quickly. Thank you!
