I have exactly the same issue. I did download the log analyzer and ran it - but it reported no issues?
What is intresting is that I access this from the cloud and have configured all apps to be downloaded to a download directory. On my windows 7 start menu - if I run speedgrade - it tries to run a version in that download directory. Howvever I checked my program files directory and see a copy of speedgrade in there too. If I run that be double clicking it - it runs without issue.
I originally thought the download area was a temporary holding area for cloud installs - so I'm suprised my start menu is configured to run from that loacation (and that the download location contains uncompressed files). I must have set up something incorrectly during the initial instal.
Can I delete these Adobe files in my download area?
I have branched this to a new discussion as it appeared that your primary concern seemed to be regarding the install location. Depending on the application installed there maybe shared components still installed in the Program Files directory. To customize the installation location you will want to open the Adobe Application Manager, from your Start Menu, and go to Preference to select a different installation location.
For the Start Menu it just contains shortcuts to the different applications.
Finally if you are receiving an error on launch but your install logs do not report an error then the installation was likely successful. It is likely that you are running into another issue which is causing your current difficulty. I would recommend posting/searching for the error in the forum related to that specific application.
