The error code 0x80070643 that you are encountering while trying to install vc_redist.x64 typically indicates that there is an issue with the installation process, which can often be related to a corrupted installation cache or a problem with the path used during installation.

To resolve this issue, you can try the following steps:

1. Check for Double Byte Characters: Ensure that the path where you are trying to install the Visual C++ Redistributable Package does not contain any double-byte characters. This can cause issues during installation.
2. Run as Administrator: Make sure you are running the installer as an administrator. Right-click on the installer and select "Run as administrator".
3. Clear Installation Cache: If the installation cache is corrupted, you can clear it by following these steps:

• Close any running instances of Visual Studio.
• Open an elevated Command Prompt (Run as administrator).
• Navigate to the installation cache directory by typing cd C:\ProgramData\Package Cache.
• Clear the cache by executing the commands:

Delete /F /S *.msi
Delete /F /S *.cab

• Try installing the vc_redist.x64 again.

4. Re-download the Installer: If the above steps do not work, consider downloading the Visual C++ Redistributable Package again from the official Microsoft website to ensure that the installer is not corrupted.

If you continue to experience issues, please check for any additional error messages that may provide more context about the failure.
