Sources of HTMLS Problems


Troubles Opening HTMLS Files

Notepad++ Removed

If you attempt to load your HTMLS file, you experience a message such as "Can't Open HTMLS Files". When this happens, it is commonly due to Notepad++ missing in %%os%%. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.


Tip: If you have another software that you know opens HTMLS files, you can select it by hitting the "Show Apps" button.


Obsolete Version of Notepad++

In other instances, your HTML With Server-Side Include file version may not be supported by your version of Notepad++. If you've got the wrong version of Notepad++ installed, you'll need to install the correct version. Your HTML With Server-Side Include file was probably created by a newer release of Notepad++ than what's currently installed your computer.


Tip: Sometimes you can get a clue about the version of HTMLS file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).


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


Other HTMLS File Opening Causes

You can still experience errors opening HTMLS files even with the latest version of Notepad++ installed on your PC. If you are still having problems opening HTMLS files, there may be other issues that are preventing you from opening these files. Problems unrelated to software:

  • Corrupt Windows Registry file path references for HTMLS
  • The HTMLS file description within the Windows Registry was removed
  • Invalid installation of a HTMLS-associated program (eg. Notepad++)
  • Something has caused file corruption of your HTMLS
  • Your HTMLS has adversely impacted by malware
  • HTMLS-related hardware has device drivers that obsolete
  • Too many applications are open on your PC to load your HTML With Server-Side Include file successfully
