Legacy Enhancement Apps

Sharpen AI, DeNoise AI, Adjust AI & JPEG to RAW

Legacy Application Notice
Sharpen AI, DeNoise AI, Adjust AI, and JPEG to RAW are discontinued legacy applications. They are no longer actively developed or supported.
Changes to operating systems, computer hardware, security requirements, and third-party applications may prevent these products from working correctly. Compatibility with newer systems is not guaranteed, and troubleshooting options are extremely limited.

Compatibility

Meeting the original system requirements does not guarantee that a legacy application will function correctly.

Operating-system updates, graphics-driver changes, authentication changes, security requirements, and newer hardware may prevent these applications from installing, launching, or processing files as originally designed.

Review the Legacy System Requirements before attempting to install or troubleshoot a legacy application.

Legacy System Requirements

Legacy Topaz applications may also fail to work as plugins in current versions of Adobe Photoshop, Lightroom Classic, Photoshop Elements, and other third-party applications. Compatibility with current or future host applications is not guaranteed.

Sharpen AI and DeNoise AI

Sharpen AI and DeNoise AI were discontinued in late 2023. No compatibility updates have been released since that time.

Known compatibility issues include:

Failure to install or launch
Crashing during startup
Indefinite loading after login
Flickering or flashing interfaces
App-data and folder-permission errors
Missing model downloads
Plugin installation or launch failures

Sharpen AI and DeNoise AI have known conflicts with macOS Sonoma and later.

Their sharpening and noise-reduction functionality is available in currently supported Topaz applications.

Adjust AI

Adjust AI is discontinued and does not receive compatibility updates.

Its last supported macOS version is macOS 10.15 Catalina. Adjust AI is not compatible with newer versions of macOS, Windows, or current Adobe applications.

Many of its visual effects can be recreated manually in Topaz Studio 2 using a combination of the following filters:

Precision Detail
Precision Contrast
HSL Color Tuning
Basic Adjustment
ReStyle

Topaz Studio 2 is also a discontinued legacy application. Compatibility with newer computers and operating systems is not guaranteed.

JPEG to RAW

The last compatible macOS version for JPEG to RAW is macOS 13 Ventura.

JPEG to RAW may fail to install, launch, or process files on newer versions of macOS or newer computer hardware.

There is no direct replacement for JPEG to RAW. Because the application is discontinued, Topaz Labs cannot provide updates, fixes, or workarounds for compatibility issues on newer systems.

macOS Tahoe

Sharpen AI, DeNoise AI, Adjust AI, JPEG to RAW, and other legacy Topaz applications may not function on macOS Tahoe.

There is no known workaround, and compatibility updates will not be released for discontinued applications.

Limited Troubleshooting

Only the following best-effort troubleshooting is available:

Uninstall the application.
Remove its remaining preference or configuration files.
Restart the computer.
Download a fresh installer from Legacy Product Downloads.
Reinstall the application.
Launch it once as a standalone application before attempting to use it as a plugin.

Legacy Product Downloads

These steps are not guaranteed to resolve compatibility issues.

Sharpen AI and DeNoise AI Troubleshooting

Windows Clean Reinstallation

Launch failures on Windows are most commonly caused by driver changes, a corrupted installation, or legacy registry entries.

Uninstall Sharpen AI or DeNoise AI using Add or Remove Programs.
Remove the application’s remaining registry entries.
Restart the computer.
Download a fresh installer from Legacy Product Downloads.
Reinstall the application.
Launch it once as a standalone application.

Use caution when editing the Windows Registry
Incorrectly editing or deleting registry entries can affect system stability. Only remove entries associated with the Topaz application being reinstalled.

If the application continues to crash or will not launch after completing these steps, no further troubleshooting is available.

macOS Clean Reinstallation

Launch failures on macOS may be caused by corrupted preference files or operating-system incompatibility.

Close the application.
Move the application from the Applications folder to the Trash.
Remove its associated .plist preference files.
Restart the computer.
Empty the Trash.
Download a fresh installer from Legacy Product Downloads.
Reinstall the application.
Launch it once as a standalone application.

If the application still will not launch, no supported fix is available.

macOS App-Data and Permission Errors

“Could Not Save App Data”

This error may appear when Sharpen AI or DeNoise AI cannot create or modify the files required to run.

Close the application.
Open Finder.
Select Go > Go to Folder.
Enter:

~/Library/Application Support/Topaz Labs LLC/

Confirm that a folder exists for the application.
If the application folder is missing, create it manually.
Reopen the application and allow any required models to download.

If the error continues, perform the macOS clean reinstallation above.

If a clean reinstall does not resolve the error, no further troubleshooting is available.

“Not Writeable”

This error means macOS is preventing the application from writing to the Application Support folder.

Close the application.
Open Finder.
Select Go > Go to Folder.
Enter:

~/Library/Application Support/

Locate the Topaz Labs LLC folder.
Right-click the folder and select Get Info.
Under Sharing & Permissions, confirm that your user account has Read & Write access.

If your account does not have Read & Write access:

Click the lock icon and enter your Mac password.
Change your user account to Read & Write.
Select Apply to enclosed items from the action menu.

If the Topaz Labs LLC folder does not exist, create it and give your user account Read & Write access.

Reopen the application and try again.

Known Legacy Behaviors

Flickering or Flashing Interface

Sharpen AI and DeNoise AI may display a flickering or flashing interface on newer systems.

You may try:

Exiting full-screen mode
Resizing the application window
Changing the display refresh rate

These steps are not guaranteed to resolve the issue.

The interface behavior should not affect the quality of exported images, but there is no permanent fix available.

If the application continues loading or spinning indefinitely after login, the behavior is typically caused by system incompatibility or a deprecated authentication service.

There is no supported fix for indefinite loading after login.

Plugin Does Not Appear or Launch

If a legacy plugin no longer appears or opens after updating Photoshop, Lightroom Classic, or another host application:

Launch the Topaz application as a standalone program.
Confirm that the standalone application opens successfully.
Reinstall the Topaz application using the installer from Legacy Product Downloads.
Restart the third-party host application.

If the plugin still does not appear or launch, it is likely incompatible with the installed version of the host application. No additional plugin troubleshooting is available.

Adjust AI and JPEG to RAW Troubleshooting

Troubleshooting for Adjust AI and JPEG to RAW is limited to a clean reinstallation.

No further troubleshooting is available if:

The application will not install or launch.
The application cannot process or export files.
The operating system is newer than the compatibility listed above.
The application does not function after a clean reinstall.
The application no longer works as a plugin in an updated third-party host.

Topaz Labs cannot provide compatibility updates or additional workarounds for these discontinued applications.
