I used to use Vault Client and just uninstalled it. I now downloaded VaultServer_3_1_1.msi and when I run it it says "IIS Version 5.00 or greater is required to install the Vault Server. Please ensure it is installed and run this install again."
I already went through the registry and deleted all relevant references to Vault. This on WinXP with SP2.
Can't install Vault Server

At the time I didn't know what IIS was. The short error message and acyronym only frustrated and confused me, while doing nothing to help me resolve the problem. If instead of that, a window displayed that defined and stated the problem, along with the solution, I would be using Vault right now instead of Perforce.
