The following steps outline the procedures for installing the Additional Account Info tab on a 64 bit system.

  1. Download Account Lockout and Management Tools from It appears that this link is no longer valid. The file can be located here:
  2. Extract the files. Move or copy acctinfo.dll from to C:\Windows\SysWOW64.
  3. Open a Command Prompt and navigate to C:\Windows\SysWOW64
  4. Run regsvr32 acctinfo.dll.
  5. Open Active Directory Users and Computers in the run dialog box: dsa.msc -32
To ease access to the 32 bit Management Console, a shortcut can be created for dsa.msc -32:

  1. Right click the location where you would like the shortcut to appear.
  2. Choose new shortcut, and set the location to dsa.msc -32.

Note: When registering a 32 bit DLL, you must run the regsvr32.exe file that exists in SysWOW64. By default, running regsvr32.exe will execute the regsvr32.exe from C:\Windows\System32. That executable is 64 bit, and will fail when trying to load a 32 bit DLL.

This does not work on Windows 8.1 x64. The error message "An attempt was made to reference a token that does not exist." will be produced.
