Can't extract Photoshop CS5

Question

I can't extract the Photoshop CS5. Everytime I try I get :"A problem occured while extracting some files. Check available space on your computer and the write privileges on the destination folder" .
I've spent long hours on the phone with multiple agents trying to resolve this issue. I have WinZIP, my computer is Windows 7 Pro, etc... Still cannot get the issue resolved. Can someone please help?
As well, while on the phone with one of the Adobe Agents, I was informed to type in: "cmd.exe" in the start menu, then once the window opened I was then informed to type: "net user administrator /active:yes". This created a whole new Administrator account for me, when I already had an Administrator account saved under my name. So now I'm stuck with two and I cannot get rid of the Administrator account that the Adobe Agent made me create. I've tried many things in reference from google. Such as: Right Clicking Computer on the start up menu then clicking manage Local Users and Groups. I then clicked Groups and tried to delete the Administrator account, however it would not allow me. Then I tried to type in "cmd.exe" in the Start Menu, once the window opened I proceeded to type: "net user administrator /active:no", and yet again it did not work. Can someone please help me remove this Administrator account as well please?

No, I turned off them all off and I still cannot extract the downloaded file.
Great. Those active, real-time scanning programs can cause all sorts of issues.
I've tried to download them to many different drives and folders including Desktop
For others, or for next time, the Desktop folder has some special properties, and those can be problematic for many programs. I suggest keeping that one clean, and not using it for such operations.
This afternoon Adobe installed Windows Installer Package and managed to Extract CS5.1; however, when I enter the serial number I get Error Message: "The serial number you entered is valid, but our qualifying product cannot be found on this Computer".
The first part is great news, and solves the originally listed problem.
For the S/N, however, there are some additional questions:
Was this an Upgrade, that you downloaded?
Do you have a qualifying copy of PS, to upgrade from?
I have never installed, or upgraded from a download, so do not know how that might function, but with the program on physical media, there are two S/N's. One is for the installer, and that S/N will tell the installer if one is doing an upgrade, or an initial install. With an upgrade, one will usually need the S/N from that qualifying program. For any S/N issue, that you cannot find a quick answer for, I strongly suggest calling Adobe Customer Support (not Adobe Technical Support), with all of the invoices, S/N's, etc., handy. They can handle most S/N issues quickly, so long as the user has the necessary numbers and paperwork.
Good luck,
