I have been trying to upgrade SA2000 from 5.5R to 6.2 but I keep getting this message "Verifying package integrity ................. failed" everytime. I tried using both Firefox and Explorer to download the SA install package but the result is the same and from release note I see that 6.2 supports SA2000...

There is a possiblity that you are trying to upgrade an old SA1000, although it looks like an SA2000.
If that's not the case:in the mentioned posting, you'll find that you you have to upgrade to 6.1 first.
BTW: Please verify that your download's MD5 matches the MD5 hash provided. On the download page, you'll find a link 'MD5' that will provide you with a long string of numbers and characters If you make an MD5 hash of your downloaded file, it should be exactly the same.
