A user on another forum got rid of the service problem by installing the Visual C++ Runtime 2008: http://www.microsoft.com/downloads/d...displaylang=en (make sure to choose x86 or x64 based on your OS)

@Jam: Thanks for the confirmation, I thought it'd work because there is not that much of a change from Vista to Win7 (on the API side at least).

@largon: Thanks for clearing that up. Please note that if you click the Apply button inside the service dialog, the service is stopped (if it is running) and optionally restarted (if any checkbox is checked), so these changes are applied immediately, no need for a reboot. Additionally, you can always enter the services control panel and disable the PhenomMsrTweaker service or set it to start manually.
