Resolved Yet another Windows Installer problem

I have seen many cases of Windows Installer problems since SP3, but I think this one is different and unanswered.

After trying various ways to fix my WinInstaller, I decided that I was going to uninstall it and then reinstall it. I followed these exact steps, triple checking to make sure I uninstalled everything: http://support.microsoft.com/kb/315346

Now, when I try installing Windows Installer 3.1 I get this message:

"Setup has detected that the Service Pack version of this system is newer than the update you are applying. There is no need to install this update."

Thus it does not install the program.

This confuses me in a few ways, in that I am trying to install Windows Installer, not a SP. Perhaps this is for SP2?. But I have followed various steps on the Microsoft support pages to determine which package to install and download, and this has to be the one. I am running Windows XP SP3 Home addition (I think 64-bit.. It doesn't say it under my OS, but my processor is AMD64. Maybe this is where I am wrong?) Maybe there is no redistribution for SP3 yet?

Anywho, so now I am stuck with a broken Installer that receives "Error 1719" when I try using it, and no way as of yet to fix it. Technically I don't have an Installer to use. I cannot rename registries in my MSIService, because I DO NOT HAVE IT. I cannot enable the service because again, I DO NOT HAVE Windows Installer at the moment. It was uninstalled lol.

Is there somebody that can help me out? I have searched for hours with no answers. I thought about uninstalling SP3, but I'm scared that something will get *******. My system restore is not working for some reason, AND I do not have a boot disc. So Yea you can see why I'm iffy about uninstalling SP3.

 

It looks like that version of WI is what I needed. That's weird becuase all I could find is the 3.1 version. Glad that it's all settled though. Thanks a lot for the help!
