Further to my previous post regarding renaming AecCore.crx, it has been suggested that this could break other things. A slightly “better” patch would be to copy the AecCore.crx from the 2013 install and place it into the 2014 folder. This does work and no visible breakage yet!
Our CAD support people have suggested that this patch is a reasonable temporary solution though they say if an update from AutoDesk arrives then you will need to revert back to the 2014 version of the AecCore.crx file before installing the update.
Also the CAD support people looking at this flickering issue with AutoDesk at the moment and I will let you know the outcome of that.
