As BAPCo benchmarks such as SYSmark and MobileMark include all the applications required to run the benchmark(s) users must be certain that any previous installation of those same applications are completely removed from the OEM preload prior to attempting to install a BAPCo product.
Microsoft provides a tool for removing Office installations. Please use this tool prior to installing any BAPCo benchmark on systems where Office is preinstalled.
Note, there may be other applications, ie, Adobe Creative Suite that will need to be removed as well. This FAQ item covers MS Office only.
