Troubleshooting AVX, DLL, or Installer Errors (Windows)

If you encounter any of the following errors while installing or using Topaz Photo, follow the troubleshooting steps below:

“Your CPU must support AVX instructions to install this program.”
“Error status 0xc0e90002”
or any .dll installer errors

These errors are usually related to Windows Smart App Control, missing AVX support, outdated Microsoft Visual C++ runtime components (MSVC), or incomplete Windows updates.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

⬇️ Choose below whether the error occurs during installation or while using the app:

Step 1: Confirm AVX Support

Topaz Photo requires a processor that supports AVX instructions.

If you already had Topaz Photo 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, send your System Profile to Support and we can confirm whether your processor supports AVX instructions:

How To Obtain Your System Profile (Windows)
Send the dxdiag file to support@topazlabs.com

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These installer errors are commonly caused by outdated or missing Microsoft Visual C++ runtime components.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

Visual C++ | x64 | Download

Once installed:

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

`Make sure 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

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

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

Step 4: Turn off Windows Smart App Control

If errors remain Topaz apps use Windows Installer Transform (MST) files during installation and updates. Windows currently does not provide a way for MST files to be digitally signed, which can cause Smart App Control to block files required by the Topaz installer.

If you receive an error while installing or updating:

Open Windows Security.
Go to App & browser control → Smart App Control settings.
Turn Smart App Control off.
Run the Topaz installer or update again.

This does not mean the Topaz installer is unsigned. This is a current Windows limitation specific to MST files.

Still Having Issues?

If the issue persists after completing the steps above, try the following:

Right-click the installer and select Run as Administrator.
Temporarily disable the firewall (present on every machine) and antivirus, then retry the installation.
Ensure you have sufficient free disk space available on your system drive.
Install Topaz Photo to the default location on the C: Drive. Installing to a network drive or external drive is not supported and can cause installation issues and plugin issues.

If the issue still remains, please contact the Support Team so we can continue troubleshooting. Send an email to support@topazlabs.com and include:
