Troubleshooting AVX, DLL, or Installer Errors (Windows)

If you encounter any of the following errors while installing Topaz Photo:

  • “Your CPU must support AVX instructions to install this program.
  • Any .dll installer errors

These errors are usually related to missing AVX support, outdated Microsoft Visual C++ runtime components (MSVC), or incomplete Windows updates. Please follow the steps below to resolve the issue.

Step 1: Confirm AVX Support

Topaz Gigapixel requires a processor that supports AVX instructions.

If you already had Topaz Gigapixel installed previously and are only updating versions, this confirms your machine supports AVX instructions. You can proceed to Step 2.

If Topaz Photo has never been installed on this machine, or if you want to confirm your CPU has AVX instructions, you can use our PC check tool

Alternatively, you can send your System Profile to Support and we can confirm whether your processor supports AVX instructions:

Important: Snapdragon/ARM Windows machines do not currently support AVX instructions. If you have a Snapdragon/ARM Windows machine, ensure to use the Snapdragon installer in your Apps Page, and not the Windows one.

Step 2: Update Microsoft Visual C++ (MSVC)

These installer errors are commonly caused by outdated or missing Microsoft Visual C++ runtime components.

Download and install the latest MSVC package here:

Once installed:

  1. Reboot your computer
  2. Retest the installer from your Apps Page.
    If you own a Legacy App, you can find your Legacy installers here.

- Ensure to use the correct installer type:
- Windows installer for Intel or AMD processors
- Snapdragon installer for Qualcomm/ARM processors`

Step 3: Install All Windows Updates

To perform if the first two steps didn't work.

Check if your machine is fully updated before installing the app. Check both locations below:

  • Settings → Windows Update
  • Settings → Windows Update → Advanced Options → Optional Updates

Install all available updates from both location, reboot your machine, then retest the installer from your Apps Page

Once all updates are installed, reboot your computer and retest the installer.
