Mach5.sys driver not working under Vista SP1



Mach5.sys driver not working under Vista SP1


The installation of Vista sp1, disables the operation of the Mach5.sys driver that DevPartner Java and DevPartner Studio use for Performance Profiling. This behavior will occur whether the DevPartner Products are installed before or after the Vista Service Pack is installed.

Users will note that DevPartner Java's Performance Analysis tool will not calculate the Methods Wait Times and will the Performance Snapshot will not display the "Methods Spending the Most Time Waiting graphic".

Also, DevPartner Studio's Performace Expert will not launch, and report a Mach5.sys driver error.

A updated Mach5.sys is available from Frontline under the DevPartner section labled "Performance Timing Driver fix for Vista SP1"
