THE INFORMATION IN THIS ARTICLE APPLIES TO:

• CuteFTP, v9.x

SYMPTOM

Upon upgrading, the following error is presented:

The program can't start because api-ms-win-crt-stdio-l1-1.0.dll is missing from your computer.

WORKAROUND

This error indicates that the C++ redistributable is not installed. This is not a problem that is unique to CuteFTP.

The problem is that the KB2999226 (Universal CRT), which is part of the Visual C++ Redistributable, failed to install. The Universal CRT fails to install if the necessary prerequisites (other updates) have not been installed yet.

1. Install Windows Updates:
1. Right-click the Start icon, then click Settings.
2. In Windows Settings, click Update & Security.
3. Check for updates and install all available updates.
4. After the updates are installed, restart your computer.
2. After the restart repeat the steps above again until no more updates are available.
3. Download the Visual C++ Redistributable:
• For Windows 64-bit: Visual C++ Redistributable for Visual Studio 2017 (64-bit)
• For Windows 32-bit: Visual C++ Redistributable for Visual Studio 2017 (32-bit)
4. Run the vc_redist.x64.exe (64-bit) or vc_redist.x86.exe (32-bit) and select Uninstall
5. Run the .exe again and select Install.
