You may not be able to open the User Accounts item in Control Panel on a Microsoft Windows XP-based computer. This behavior may occur if certain .dll files are not registered correctly. Additionally, you may receive an error message that resembles the following:
Wrong number of arguments or invalid property assignment
To fix this problem, use the regsvr32 command to register the .dll files. To do this, follow these steps:
1. Click Start, click Run, type cmd, and then click OK.
2. At the command prompt, type the following commands, press ENTER after each command, and then click OK when a message says that the registration is successful:
C:\> Regsvr32 jscript.dll C:\> Regsvr32 nusrmgr.cpl C:\> Regsvr32 /i mshtml.dll C:\> Regsvr32 themeui.dll C:\> Regsvr32 Vbscript.dll
Now, check whether you can open the User Accounts item in Control Panel.
