I don't think this is a problem on my side...any ideas?
It's my understanding that an "invalid checksum" error is a suggests that the file that you are trying to access is corrupt/damaged in transit to your computers disk. This could be because of an issue with network connection (yours or ours), or possibly damaged hardware. There's a disscusion on Apple's forums about troubleshooting this issue that might help you solve your problem:

Hold on. the fix you're suggesting is from 2008! how does this have any bearing on an issue in 2011-2012? i've tried to download and install a trial of photosp elements for 8 hours!!! i have a 100mb internet connection so download only takes a few minutes, but i've done it 6 times now and without success. everytime i get an invalid checksum error. i've tried downloading from US, UK and Germany and always the same error - VERY frustrating. i've read the blogs and none of the suggestions work - even downloading on one mac and transferring the file to another for install.
any up to date advice?
Go to Finder > Type Disk Utility > Preferences and simply unchecking the box that says "Verify Checksums" . Close Disk Utility. Then PSE dmg should open fine and the program should install without any issues.
(You might want to re-check the verify checksums box after you've finished the installation though because it's there to help prevent the installation of corrupted .dmgs that could potentially harm your computer)
So I did what you said and the installation got part way through before encountering errors...
i have 750mb of space so no issue there. any other ideas? As I said, 6 times I've downloaded the file and the same error every time and I got rid of cookies etc that was suggested in another blog
download from here :-
and then .....It will be faster then before it is direct download link without the download manager
I am having the exact same problem. I also accidentally downloaded Elements Premier (after the first Elements had a checksum error) and it installed just fine. I downloaded Elements again and it had the same checksum error. I'm now trying the direct download site suggested. I hope it works. No need to buy this product if I can't install it in the first place - and I really want to buy it.
