I have chosen Updates from the Help drop down menu. Eight updates were listed. I proceeded to install all eight. One failed- ACR 5.6 Update. Canon EOS7D.
All Windows Updates (including Optional) have been installed. Windows Vista Home Premium 64-Bit. I have run CCleaner, rebooted the system and tried again, only the ACR 5.6 update is offered and it fails to install.
Any help will be appreciated.
