I have tried this installation a number of times now and continually get a problem with kb403891r2 error regarding the UninstallColorProfilesRollback preventing the installation.
I have tried both solutions I was taken to by the Adobe Support advisor regarding manually removing the files and setting the permissions in the registry.
I have also tried changing the permissions on the relevent folders as per the information found on these discussion pages, still to no avail.
I am running Windows 7 Home Premium on an Intel i7 system.
Hope you can help as I am about to lose what little hair I have left!
Thank you so much, this gave me the clue I needed. The problem was based on my using multiple monitors, one of which is connected to an HDMI connection with obviously a separate colour profile.
Restarting the computer with only the VGA connected monitor active allowed me to remove all of the colour profiles and the installation subsequently went without a hitch.
Thanks again for the information.
