Download and install Lightroom 4 on Mac

I bought 4 LR on the Adobe site and received the email with the link to download.  I downloaded the Mac version on my computer but the installation program is unable to open it.  I get the error message: impossible operation completed (error com.apple.installer.pagecontroller - 1).

Cannot open the 'Adobe Photoshop Lightroom 4.pkg"

Any ideas on how to solve this problem?  Thank your for your time and your consideration!

LR4 works 10.6.8 and later, so yes, the LR4 has high specification compared to LR3.

It is best if you check the specs of youeself, I gave the link in my previous post.

Also, you wrote: -.

Usually, I get an error message indicating that Mac does not meet the requirements when this is the case.

That's when the Adobe installer start and run the system check, but here, the error is thrown by the Mac itself before initializing the installation of Adobe.
