I've put MSICabExtract.exe and MSICabExtract.txt inside HFTOOLS.
The HF folder contains one MSI file, but it's not being processed if I can believe ERROR_REPORT.TXT (the file is not in the list of files for the HF folder).
The file's name is install_flash_player_active_x.msi. In a second attempt, I've renamed the file to flash8ie.msi thinking it maybe has to be in the 8:3 format but it didn't help.
Am I doing something wrong or is the file not supported?
