CHK File Complications
Troubles Opening CHK Files
Sophos is Not Installed
If you attempt to load your CHK file, you experience a message such as "Can't Open CHK Files". When this happens, it is commonly due to Sophos 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 don't have Sophos installed, and you know of another program to open your CHK file, you can try opening it by selecting from the programs listed under "Show Apps".
Outdated Sophos
In other instances, your InterCheck Checksum Database file version may not be supported by your version of Sophos. If you've got the wrong version of Sophos installed, you'll need to install the correct version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.
Tip: Investigate your CHK file by right-clicking and selecting "Properties" to find clues on what version you need.
Summary: Not having the right Sophos version on your computer can cause problems opening CHK files.
