Important Information for WinTool Users from Version WT2025.1 Onward – Compatibility Issue after Windows Update

Currently, some users from Version WT2025.1 may experience startup problems after installing the latest Windows update, specifically .NET 8.0.17 Security Update (KB5061935).

After applying this update, WT2025.1 may no longer start on certain systems. Older WinTool versions are not affected.

The root cause is an incompatibility introduced by the .NET 8.0.17 runtime update, which prevents required components of WT2025.1 from loading correctly.

Your WT2025.1 installation is not damaged. No changes to the program code are required.
