VTDiag v0.2.0-beta (one-click fixes)

VTDiag v0.2.0-beta: one-click fixes. Made for r/ValorantTechSupport. Not affiliated with Riot Games.

New in v0.2

• Fix button works: VTDiag changes the setting, service or registry value for you. Every fix explains what it does, asks for your consent, backs up what it changes, checks that it worked, and can be undone from Undo changes.
• No setup: the first time you press Fix, VTDiag copies itself to C:\Program Files\VTDiag and reopens. Windows asks for permission once for the copy and once more when it reopens (fixes need administrator rights, and VTDiag only runs them from Program Files, where other programs can't tamper with it).
• Tested for real: all 32 fixes are applied, verified and undone on a real Windows machine in CI on every change.
• The scan itself still only reads. "Do it yourself" steps (EN/TR) are still there for every fix.

How to run

1. Download the zip.
2. Extract it to its own folder.
3. Run VTDiag.exe. Windows 10/11 x64 is required; .NET is included.

SmartScreen may warn you because the app isn't code-signed yet. Click More info → Run anyway.

Remove: delete C:\Program Files\VTDiag (undo your fixes first if you want them reverted).
