Sources of LESS Problems


Typical LESS Opening Challenges

Adobe Dreamweaver Removed

When you double-click your LESS file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to Adobe Dreamweaver missing in %%os%%. The OS won't know what to do with your LESS file, so double-clicking to load the file doesn't work.


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


Obsolete Version of Adobe Dreamweaver

Occasionally, you might have an outdated version of Adobe Dreamweaver installed that's incompatible with your LESS Style Sheet type. If you've got the wrong version of Adobe Dreamweaver installed, you'll need to install the correct version. This issue mainly occurs when your LESS Style Sheet file was created by a newer version of Adobe Dreamweaver than you have on your PC.


Tip: If you right-click on your LESS file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.


Summary: Not having the right Adobe Dreamweaver version on your computer can cause problems opening LESS files.


Other Causes of LESS File Opening Problems

Errors opening LESS Style Sheet files can still occur even with the latest Adobe Dreamweaver software installed on your computer. If you are still having problems opening LESS files, there may be other issues that are preventing you from opening these files. Problems unrelated to software:

  • Windows Registry LESS file paths that are incorrect
  • Accidental deletion of the description of the LESS file in the Windows registry
  • Adobe Dreamweaver or another LESS application experienced a flawed installation
  • Something has caused file corruption of your LESS
  • The LESS is infected with a virus
  • Device drivers for LESS-related hardware are out-of-date
  • Your PC doesn’t have enough available resources to open the LESS Style Sheet file
