Hey everyone,

I have sort of a weird problem going on and I am hoping that someone can come up with the solution.

I have a Dell Inspiron 1721. A few days ago, I decided I was done running Windows Vista and wanted to jump back to XP. I pulled out my Professional disc, and started it up. I formatted the hard drive and removed all partitions (which I now realize was a mistake). Shortly after installing XP, I found out that my video hardware (ATI Radeon Xpress 1270) and my audio hardware (SIGMATEL X-HD Audio) did not have a driver for XP and never would. So, I had to wipe XP and use Dell's packaged restore disc to get my computer back to Vista.

Then, the problem cropped up. Anything I download off the internet seems to give me an error, ranging from invalid checksum to corruption to NSIS. Note that programs that I downloaded on my first Vista iteration that were saved to my portable hard drive install without any issue. This happens with both Internet Explorer and Firefox. Initially, when I thought that I could fix the problem by downloading and reinstalling the Windows Installer Redistributable v3, I tried downloading it on another computer and moving it to here, but it gave me a different error that there was not enough space on the hard drive (there are 138 free GBs). I'll also note that in neither Dell's Vista disc nor the one I own did it install "installer.exe" to the C:\Windows directory.

I have tried everything I can think of, but so far nothing has taken. Here is what I have tried:

1. Reinstalling Windows Vista from Dell's support disc
2. Reinstalling Windows Vista from my own personal (legal) copy
3. Turning off Windows Firewall and Windows Defender
4. Installing an updated version of NSIS (2.3)
5. Ran Dell's Extended Diagnostics (more important, all hard drive tests passed)

So, can anyone help?
