UNREGMP2.EXE – entry point not found, the Procedure entry point GETIUMS could not be located in the Dynamic link library MSDART.DLL.

You could come across this issue when you install Windows XP (clean install or Repair install). This occurs only when you install the original Windows XP (without service packs)

To fix this problem, use a Windows XP installation disk with a Service Pack (SP1 or SP2) or try the following in order (proceed to next solution, only if the previous fails):

Solution 1:

1. Press SHIFT+F10 to bring up the command prompt.

2. Type Taskmgr.exe in the DOS window and press enter. This will open the Task Manager.

NOTE: If this doesn’t work, try CTRL+SHIFT+ESC.

4. In the Task Manager, select the error message window in the Application list and click End Task.

5. Click the Processes tab and select the process UNREGMP2.EXE and click End Process.

6. Exit the Command Prompt and resume the installation process.

This should help.

Solution 2:

Hold the CTRL key and keep clicking the OK button on the UNREGMP2.EXE error message. To be honest, this may take from a few clicks to a couple hundreds of clicks. Hence, have patience to get rid of this error.

Solution 3:

Another solution would be to start the computer with the Windows XP CD and get to the Recovery Console and rename the MSDART.DLL file (to say MSDART.DLL.OLD).

To do this,

1. Logon to the Recovery Console. Click Here to find how to log onto Recovery Console.

2. Once in, type

3. Type Exit to exit the Recovery Console and restart the computer.

This should fix the problem. As I said earlier, this problem is later fixed in Windows XP SP1 so if you are using Windows XP installation CD with a Service Pack (SP1 or SP2) then there shouldn’t be a problem.

  1. I’ve got this issue (Unregmp2.exe) having installed Win XP Service Pack 3. I now cant re start or repair my windows installation because of it. Or even run in safe mode.

  2. Strange you had this issue in SP3. But, if the problem happened during the install/repair procedure then the above shoul still work!!!

  3. 1st solution worked! thanks!

  4. Can’t start WMP. Whenever I try to start it, it goes off immediately, even before the start.

  5. Can’t start WMP. Whenever I try to start it, it goes off immediately. Got the iformation that WINDOWS\inf\unregmp2.exe/ is missing.
    How can I reinstall it, please?

  6. Brilliant info,had a problem but quickly solved.Thanks

  7. I had the same exact error window entitled “unregmp2.exe Entry Point Not Found”. Error message was “The procedure entry point GetIUMS could not be located in the dynamic link librry MSDART.DLL.”
    HISTORY: I did a clean Win XP install from a CD without SP1 (an early Win XP CD) and the install went perfectly until I downloaded SP3 and installed it. Upon reboot, it never fully booted up again. Upon subsequent reboots standard and safe mode were simply a black screen, with mouse working. I felt that I had no choice other than to try a reinstall over the old install and that’s when I got the infamous error message above. Initially, I dead a complete drive format before the initial install to ensure that the drive was clean and to help the install go smoothly. I had another error message before the install completed and I used the same Shift+F10 and taskmgr.exe to get rid of the message and continued the install.
