I then ran the web installer. This fails with "General Error" and does not give a code. I downloaded the standalone "Install_Flash_player_AX.exe" file and ran it (I have IE11) and it then gives the following error:
A required file (C:\Windows\SysWOW64\Macromed\Flash\FlashUtil32_15_0_0_239_ActibeX.exe:1260) could not be installed.
Please let me know if there are any log files needed and what folder I should grab them from.
