Hi,
I have been trying to get this going on and off now for a month!
I have a cloud membership.
I have a 2.5 GHz Intel Core i5 running 10.7.5. 4 GB 1333 MHz DDR3
So, I signed into Cloud, and downloaded the CS6 Master Collection. 6.9 GB, 2 + hours.
Within the folder is a file called "Install". When I try to launch this, Adobe Installer pops up and says:
We've encountered the following issues
Installer failed to initialize. Please download the Adobe Support Advisor to detect the problem.
So, I downloaded it. Then it told me to update it because there was a newer version (?), which I did.
Inspection could not identify any issues. Please contact Adobe Support for futher assistance.
At some point going around in circles, I was prompted to get AIR. Which I downloaded. It doesn't do anything that I can see.
I decided to start again - however I didn't want to download the Master Collection again. I uninstalled Application Manager, Support Advisor, Air, and my original CS3 software with the uninstall apps just in case it was interfering.
Adobe Download Assistant tells me there is an updated version. So I update to 1.2.4. The window won't go away, and I can't click on anything. So I hide it, and run the DMG. It tells me:
Sorry, an error has occurred. This application can't be installed because the installer has been misconfigured. Please contact the application author for assistance.
I am so frustrated, I feel like I am going around in circles. Now I don't even have my CS3 to fall back on unless I intsall it again of course....
By the way, I have been using Adobe since forever, Photoshop 2.5, and using computers for longer. Anybody remember Ventura Publisher? However, this is making me feel like a tool. 
I would appreciate some help.
