Hello Fjtorsol, thanks for joining the chipset community.
Would you please let me know if you are getting an error message when you start the software?
Which RST version are you using?
These are some recommendations I could give you in order to try to resolve this behavior.
• Uninstall the Intel® Rapid Storage Technology from programs and features.
• Reinstall the .NET framework
• Install a different RST version
In addition, you can also try to do a system restore if the software was working fine before.
