If you are having issues with the program, please see the help documentation that comes with it. You can get to it by pressing F1 from within the program or clicking the little question mark icon in the top right. You can also directly open the Help.chm file that comes with the installation.

The most common issue people encounter is crashing on startup. There are two common causes for this problem:

  1. You did not extract all of the files from the ZIP to the same location before running the program. Make sure you are not trying to run the program from inside of the zip. You need to actually extract ALL of the files to some location on your computer and run the program from there.
  2. You do not have all of the technology installed on your computer that the program uses. Make sure you have installed all of the third party dependencies listed in the Installation section on the download page.

A number of people have contacted me regarding the following error:

"Could not load OpenJpegDotNet.dll or its dependency openjp2.dll."

One person reported that they were able to fix the issue by uninstalling and reinstalling their C++ runtime. Please try the following:

  1. Uninstall the C++ runtime from your system by going to [Control Panel] > [Programs and Features] (Add/Remove Programs in XP). Look for "Microsoft Visual C++ 2012 Redistributable (x86) - [version]" and uninstall it.

    • If you don't see it in the list, that means you don't have it. Move on to the next step.
  2. Download a new copy of the C++ runtime from Microsoft using this link and install it. Make sure to choose the file that has "x86" in its name.
  3. Try running SLCacheViewer again.

If reinstalling doesn't work, then you may have a different issue. I cannot tell what is going wrong since I cannot get the problem to occur on any machines I have tested. If anyone is encountering this problem and is tech-savvy enough to use a program like Dependency Walker to track down which DLL is missing, please let me know so I can try to get this resolved for everyone (note: open the file OpenJpegDotNet.dll in DependencyWalker rather than SLCacheViewer.exe). I apologize to anyone encountering this issue, but there is nothing I can do without more information.
