If you have a version of Lightroom and the alert comes to tell you that a new version is available, so you down load and then when trying to run the .exe file you get the error message you may find it a struggle to find the solution.
I had this issue and the Adobe solution is to download a fresh instal.
I was running a 4.1 Beta upgrade from the original 4.0 install. I tried a second download and it didn’t work. I couldn’t find the answer online so I decided to uninstall my 4.1 Beta install and delete my 4.1 download .exe.
I then reinstalled my 4.0 off the disc, re downloaded the 4.1 update and click the .exe and this time it worked.
Hope this helps a few who’re in the same situation
