Hi all, I have downloaded a trial version of lightroom 4 to see if I want to upgrade from my lightroom3, but it wont open on my pc. It keeps asking me what program I want to use to open it with, and when I click adobe reader it tells me that it is not a supported file type or the file has been damaged! Help!???
When I click on the program download in the download file, it asks me if I want to open it. When I click open, it then asks me which program I want to use to open it with, (this window lists all programs such as Nero, internet explorer adobe reader etc) and automatically highlights adobe reader. After I click open with the adobe reader highlighted, it then tells me that it cannot open Lightroom because it is not a supported file type, or the file has been damaged! I have downloaded it twice but neither one is able to open. Thanks so much.

Can you confirm the name of the file that you are clicking on? Should be something like "Lightroom_4_LS11.exe", which is a standard executable file and shouldn't need you to select a program to use (and even if it did, Adobe Reader is the wrong thing to select).
