Sources of MST Problems


Issues Opening MST Files

Corel Presentations X8 Not Present

You attempt to load your MST file and get an error such as "%%os%% Can't Open The MST File Extension". When this happens, it is commonly due to Corel Presentations X8 missing in %%os%%. This will prevent you from double-clicking to open the MST file because the OS doesn’t know how to handle it.


Tip: If you know of another program that can open your MST file, you can try opening it by selecting the application from the programs listed.


Outdated Corel Presentations X8

It is possible that your version of Corel Presentations X8 isn't able to open your Corel Presentations Master Template File file due to incompatibility. Download the latest Corel Presentations X8 version from the Corel website to ensure you have the correct one installed. The primary cause of this problem is that your Corel Presentations Master Template File file was created by a different (newer) version of Corel Presentations X8 than what's installed.


Tip: Investigate your MST file by right-clicking and selecting "Properties" to find clues on what version you need.


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


More Causes of Problems Opening MSTs

Assuming you have the right Corel Presentations X8 version installed, other problems can prevent you from opening MST files. There can be external issues inside of %%os%% that are causing these errors when opening MSTs. Other contributing causes:

  • MST file type Registry entries are wrong
  • Accidental deletion of the description of the MST file in the Windows registry
  • Incomplete or bad installation of a software application associated with the MST format
  • Your MST file is corrupted (issues with your Corel Presentations Master Template File file itself)
  • Your MST is infected with malware
  • Device drivers of the hardware associated with your MST file are corrupt or out-of-date
  • Your computer does not have the adequate system resources to open the Corel Presentations Master Template File format
