AHU File Complications

Common AHU Opening Problems

Adobe Photoshop CC is Not Installed

When you double-click your AHU file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Usually, this is because you do not have Adobe Photoshop CC for %%os%% installed. The OS won't know what to do with your AHU file, so double-clicking to load the file doesn't work.

Tip: Another AHU-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Incorrect Adobe Photoshop CC Version

Your Adobe Photoshop HSL File file is incompatible with Adobe Photoshop CC because you might have the wrong version installed. Installing the latest version of Adobe Photoshop CC from Adobe Systems Incorporated is recommended. This issue mainly occurs when your Adobe Photoshop HSL File file was created by a newer version of Adobe Photoshop CC than you have on your PC.

Tip: Investigate your AHU file by right-clicking and selecting "Properties" to find clues on what version you need.

Summary: In either case, the majority of problems opening AHU files are related to not having the correct software application installed on your computer.

Other AHU File Issues

Even with the correct version of Adobe Photoshop CC installed, you can still experience difficulties opening AHUs. There can be external issues inside of %%os%% that are causing these errors when opening AHUs. Issues that aren't software-related:

• File references in the Windows Registry for AHU are wrong
• The AHU file description within the Windows Registry was removed
• Adobe Photoshop CC or another AHU application experienced a flawed installation
• Something has caused file corruption of your AHU
• Your AHU is infected with malware
• Hardware associated with AHU has outdated drivers
• Windows has inadequate resources to open your Adobe Photoshop HSL File file
