I have downloaded Adobe - Exchange : Download the Adobe Extension Manager Verson CS6 for Windows for the second time, Uninstalled the previous verson and reinstalled the software again. Nothing has changed. The software opens, starts like it is going to run, then stalls. I only have 1 piece of software which had been working fine. It still works fine. I allowed this screen to run overnight last night, which made no difference. Here is a screen shot of the fail.
Best trying this in safe mode in that case.
