Troubleshoot HWPML Files
Frequent HWPML Opening Issues
Missing Hangul
Double-clicking your HWPML file prompts the message "%%os%% Can't Open HWPML File". Usually, this is because you do not have Hangul for %%os%% installed. This will prevent you from double-clicking to open the HWPML file because the OS doesn’t know how to handle it.
Tip: When another HWPML application is installed, you can choose to open it by selecting "Show Apps" and using that program.
Hangul is Out-of-Date
In some cases, you might have a newer (or older) version of a Hangul Word Processor Markup Language Document file that is unsupported by your installed application version. Installing the latest version of Hangul from Hancom, Inc. is recommended. This problem is predominately due to having a Hangul Word Processor Markup Language Document file version that was created by a newer version of Hangul than what you have installed on your PC.
Tip: Right-clicking on your HWPML, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.
Summary: Not having the right Hangul version on your computer can cause problems opening HWPML files.
Other HWPML File Opening Causes
You can still experience errors opening HWPML files even with the latest version of Hangul installed on your PC. There can be other issues - unrelated to software - preventing you from opening HWPML files. These other problems include (listed in order from most to least common):
- HWPML file references in the Windows Registry are broken
- Corruption of the HWPML file description inside the Registry
- Defective install of a HWPML program, such as Hangul
- Something has caused file corruption of your HWPML
- Malware-tainted HWPML file can't be opened
- Hardware associated with HWPML has outdated drivers
- Windows has inadequate resources to open your Hangul Word Processor Markup Language Document file
