In Windows 7, how do I get around the "The file name(s) would be too long for the destination folder" error?

I am working on analyzing a large base of source code provided to me as a 5GB .zip file. I need to maintain the exact file structure when extracting, however, when I attempt to extract I get an error message saying:

The file name(s) would be too long for the destination folder.

I understand that this is due to Windows' 260 character limit on file paths, but there is a hotfix for this published by Microsoft.

I downloaded the hotfix, ran as an administrator, but then got another error:

This update is not applicable to your computer.

Well, according to the hotfix literature, it should be exactly applicable to my computer.

• Windows 7 Ultimate


• SP1


• x64

Any suggestions? Thanks in advance.
