Hello Next_Step, the reason why you are getting that error is because you have installed a version that was design for the ICH controller.
I check the chipset type of your motherboard (H55) and it is a PCH controller, so the compatible software you need to install is the following.
Please uninstall the Matrix Storage Manager v 18.104.22.1683, restart the system and download the version I sent you.
Thank you very much for your help, I will try it asap and I will let you know if this will fix my issue. Strange that Asus placed the wrong driver on the drivercd and on their website.
I’m not sure why ASUS is giving the incorrect drivers. However please try the one I send you, and let me know the results.
Thank you. I have tried it and fixed my problem!
Excellent! I’m glad to know it worked.
