MATSWiz.exe – System Error as .dll file is missing

Asked By 200 points N/A Posted on -


My problem is that whenever I run Mats_Run.Codec, an error pops up and says “MATSWiz.exe – System Error".

The program cannot start because its .dll is missing from my computer. I tried reinstalling the program to fix this problem. Like the error says I re-downloaded the software and then tried to run it but still it gives me the same error. I am currently using Windows 7 Professional 32bit. My computer is Mecer Xpression TW7M with an Intel Chipset “Intel 965 Express Chipset Family”; Ram memory 2GB. If you need to know more information, just reply to the post and I will tell you as soon as I can Thanks.

You can try two solution methods here to solve this problem. First is to run the System File Checker [SFC] to repair corrupt system files.

For this follow these steps:

  1. Run an command prompt as administrator. i. e. type CMD in the search box at start menu, right click on the cmd.exe and click run as administrator.
  2. In the command prompt, type sfc /scannow and press enter.
