Greetings Net,

When running the installer: rewrite_1.1_x86_rtw.msi
I get the following error message:

This installation package cannot be installed by the Windows Installer service. You must install a Windows service pack that contains a newer version of the Windows Installer service.

I have checked and I'm fully up-to-date on Windows Update.

I'm running Windows Server 2003 Web Edition, SP2.

Which service pack do I need to install so that I can install URL Rewrite?

Can you link us to the exact program?

Are you sure it is compatible with a 64 bit OS?

You could also take a look at the Installer Cleanup tool:

If this is what you are trying to install, according to the system requirements it is only for Windows 7, Windows Server 2008, Windows Vista Service Pack 1, and Windows Vista Service Pack 2.

Good points, looks like I don't have what it takes:

In the Requirements, it states:

* Windows Server 2008 or Windows Vista SP1; Windows Server 2008 R2 or Windows 7
* Internet Information Services 7 must be installed

And I'm running IIS 6.0 on 2003. :-(

Thanks anyway. I'll see if I can find one for IIS 6.

This was a case where I just didn't do the research; I was in such a hurry.

I researched more, found this:

But it didn't seem to do anything once I had it installed, so...

I researched some more and found this:

And this is the winner. It's specifically designed to do what I wanted to do anyway: display "pretty" PermaLinks for WordPress in IIS 6.0. Here's the info on that:

Solved.

Thanks for your help!

Thanks for the updates. Glad you worked it out.

Let us know if we can help further in the future.
