The api-ms-win-core-threadpool-l1-2-0.dll error usually happens when you try to run modern software on an older operating system like Windows 7, 8, or 8.1. It means the program requires a specific Windows API function that your current OS version does not support.
Here is how to fix it safely without downloading third-party DLL files.
1. Install Windows Updates
The most common cause is a missing system update that bridges the compatibility gap.

- Search for Visual Studio 2015, 2017, 2019, and 2022 Redistributable.
- Download and install both the
vc redist.x86.exe(for 32-bit) andvc redist.x64.exe(for 64-bit) versions. - Restart your PC after installation finishes.
3. Run System File Checker (SFC)

- Press the Windows Key, type
cmd. - Right-click Command Prompt and select Run as administrator.
- Type
sfc /scannowand press Enter. - Wait for the scan to finish and restart your computer if it fixes any files.
4. Run the Program in Compatibility Mode

- Right-click the shortcut or
.exefile of the program giving the error. - Select Properties.
- Click the Compatibility tab.
- Check the box for Run this program in compatibility mode for:.
- Select Windows 7 or Windows 8 from the dropdown menu.

5. Upgrade Your Operating System
