While installing PerformanceTest this error might appear.
C:\Program Files\PerformanceTest\DirectIo64.sys
An error occurred while trying to replace the existing file:
DeleteFile failed: code 5
Access is denied.
The DirectIo64.sys file is a device driver which is part of PerformanceTest. If you are in any doubt about the origin of the file, right click on it and check the Digital Signature.
The file is used to collect system information for the hardware in the machine. e.g. The RAM sticks model numbers, temperature data, etc..
The files is also used by several different PassMark products. If there was a sudden unexpected crash of one of these software packages then the file might be locked (as the device driver is still loaded into RAM after the crash).
The solution to unlocking the file and the error message is to reboot the machine then try the installation again.
