Unable to extract trial version of Flex Builder 3

Recently, i wanted to try out to install Flex Builder 3 from Adobe website and after successfully downloaded the file i was unable to extract the files. It came out this error “Please select another location to extract the installer”.

I checked the hard drive and i have more than 10gb spaces in all my drives. I kept getting the error no matter what. I clear my Windows temp folders, tried in different OS such as XP and vista. I also tried to disable my firewall and remove my anti-virus software.None of them is working. I suspected that the downloaded file have been corrupted.

Oh Yea. I forgot to mention that i have downloaded the file from my office computer. Apparently, the package i have downloaded have been scanned through proxy and Inter-scan anti-virus checked. That’s why the files get corrupted even i downloaded the Flex SDK packages. So, i went to my friend place and re-downloaded the files. All have been working fine without any errors.

So my conclusion is that, if you have the same error and tried the Adobe troubleshoot, and none of the steps above worked for you, you might try to re-download the packages from different computer or proxy, virus scan free.
