The common error appears when people are doing a repair install of windows. Here is how to get around it without waiting hours and hours.

When doing a repair install, XP will often give the following error message:

The procedure entry point GetIUMS could not be located

Clicking OK does nothing but redisplay this window. Several people on the internet have noticed that if you click this box enough eventually the error will go away and you can continue. Other people have noticed that if you just leave the computer alone for a while, and then you come back and click on the box, the error will go away and you can continue installation.

Here the quicker way:
1. Press Shift+F10 to open up a DOS box
2. Type taskmgr.exe and press ENTER from the command line
3. When the task mananger opens, select the Processes tab
4. Select the unregmp2.exe and end it
5. Click the Applications tab
6. Select the error window and click End Task
7. The window will close, you can exit your DOS box, and continue installation

Props goes to nihir in the windrivers forum for the idea.
