Troubleshooting Problems Opening HDT Files
Common HDT Opening Problems
Adobe Photoshop CC Disappeared
When trying to open your HDT file, you get the error "Can't Open HDT File Type". Usually, this is because you do not have Adobe Photoshop CC for %%os%% installed. Your operating system cannot associate your HDT with Adobe Photoshop CC, so double-clicking the file won't work.
Tip: When another HDT application is installed, you can choose to open it by selecting "Show Apps" and using that program.
Outdated Adobe Photoshop CC
Sometimes your installed version of Adobe Photoshop CC won't support your Photoshop HDR Toning Preset File file. Visit the Adobe Systems Incorporated website to download (or purchase) the latest version of Adobe Photoshop CC. Most of the time your Photoshop HDR Toning Preset File file was created by a newer Adobe Photoshop CC than what you have installed.
Tip: Sometimes you can get a clue about the version of HDT file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).
Regardless, most of the HDT file opening problems relate to not having the right version of Adobe Photoshop CC installed.
Additional HDT Opening Issues
Errors opening Photoshop HDR Toning Preset File files can still occur even with the latest Adobe Photoshop CC software installed on your computer. There can be other issues - unrelated to software - preventing you from opening HDT files. Problems unrelated to software:
- Corrupt Windows Registry file path references for HDT
- Accidental deletion of the description of the HDT file in the Windows registry
- Invalid installation of a HDT-associated program (eg. Adobe Photoshop CC)
- Something has caused file corruption of your HDT
- Your HDT is infected with malware
- Hardware associated with HDT has outdated drivers
- Your PC doesn’t have enough available resources to open the Photoshop HDR Toning Preset File file
