I can download, from Cloud, other Adobe products BUT when I download Lightroom 4 it will not open and gives an error message "This application was unable to start correctly (0x000007b).
Previously I had purchased, singularily, Lightroom 3 and it worked well for almost a year but suddently when I would try to open I received the same error message as above. I have tried MULTIPLE courses to try to fix this but cannot.
We cannot know. That's just Windows' most basic crash signature. Without some system details and other info nobody can tell you anything. Provide the infor from your Event Viewer and the relevant system info. That aside, if otehr Adobe apps crash as well, chances are something has damaged the licensing system or shared components and you may need to uninstall and reinstall it all...
Thank you for your reply. Other adobe apps are not a problem, i.e., Adobephotoshop, Adobe Acrobat Xi, etc. The version 3 that was initially purchased worked fine for several months and then reverted to the error message agove. When I purchased Cloud and downloaded LR4 the download was fine but again would not open. I have spent hours on the phone with tech help from India and it was a massive waste of time.... I ran a repair on Windows, downloaded 32bit version of LR3 and it seems to work some...could not find 32bit of LR4. I have installed and removed the program more than 10 times. I do not know what "event viewer" is nor where I would find it. Disappointed in the system and appalled with tech support.

No, this is a widely known error message that many users received.

Did you have iLivid installed sometime?
Because this will screw up your Windows dlls, which LR is missing afterwards.
You can get them again via Adobe from
And never use these Indian *support* folks - I have not yet heard from anyone that they have a clue... they will not even be aware of thing obvious on this forum.
No question " iLivid " is the culprit. The LR 4.3 64-bit error immediately surfaced after I - naively - installed iLivid. I believe this program did some damage to Windows, as Windows was not able to restore to the "pre-iLivid" state. IMO " iLivid " should be identified as a malware. Hours lost and very frustrating.
The problem you have is not restricted to the iLivid program.
Adobe in their advice on how to solve the problem do not mention iLivid - although some people on this forum have reported that they can open Lr after deleting iLivid from their computer.
If you had iLivid onyour computer you would know. It is a program that you download and that makes it easy to download videos from the web.
So I recommend that you think in the direction that Adobe points to:
