Understanding HPL Issues

Troubles Opening HPL Files

Canvas X Removed

When you double-click your HPL file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". If so, it typically means that you don't have Canvas X installed for %%os%%. You won't be able to double-click to open your HPL because your OS doesn't know what to do with it.

Tip: If you don't have Canvas X installed, and you know of another program to open your HPL file, you can try opening it by selecting from the programs listed under "Show Apps".

Incorrect Canvas X Version

Sometimes your installed version of Canvas X won't support your HP Graphics Language Plotter File file. Installing the latest version of Canvas X from ACD Systems is recommended. This issue mainly occurs when your HP Graphics Language Plotter File file was created by a newer version of Canvas X than you have on your PC.

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

Conclusion: The majority of HPL file opening issues are due to not having the correct Canvas X version installed.

Additional HPL Opening Issues

You can still experience errors opening HPL files even with the latest version of Canvas X installed on your PC. If you are continuing to have errors with loading HPL files, other external issues might be to blame. Other contributing causes:

• HPL file type Registry entries are wrong
• Unintentional removal of the description of the HPL file inside the Windows Registry
• Invalid installation of a HPL-associated program (eg. Canvas X)
• Something has caused file corruption of your HPL
• The HPL is infected with a virus
• Device drivers of the hardware associated with your HPL file are corrupt or out-of-date
• Too many applications are open on your PC to load your HP Graphics Language Plotter File file successfully
