  Workaround
  
  To work around this problem, you can use Registry Editor to delete the related registry entry. Then, use the Regsvr32 command to register the Mscomctl.ocx file. You can also create a batch file to automate this.
  
  Manually delete the related registry entry
  
  ImportantThis section, method, or task contains steps that tell you how to modify the registry. However, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For added protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click the following article number to view the article in the Microsoft Knowledge Base:

  To delete this registry entry, follow these steps:
   
  1. Click Start, click Run, type regedit in the Open box, and then click OK.
  2. Locate and then click the following subkey in the registry:
      
     HKEY_CLASSES_ROOT\TypeLib\{831FDD16-0C5C-11D2-A9FC-0000F8754DA1}\2.0
  3. On the Edit menu, click Delete, and then click Yes.
  4. Exit Registry Editor, and then restart the computer.
  
  
  Manually register the Mscomctl.ocx file
  
  Note You must run the commands from commands at an elevated command prompt with administrator permissions. To do this, follow these steps:
  
  
   
  1. Click Start, type cmd.
  2. Right-click the cmd icon, and then click Run as Administrator.
  3. Depending on your operating system, type the either of the following commands, and then press Enter:
     • For 64-bit operating systems, type the following:
       Regsvr32 "C:\Windows\SysWOW64\MSCOMCTL.OCX"
     • For 32-bit operating systems, type the following:
       Regsvr32 "C:\Windows\System32\MSCOMCTL.OCX"
  Create a batch file to delete the related registry entry and register the Mscomctl.ocx file
  
  You can create a batch file to delete the registry entry and register the Mscomctl.ocx file. To create the batch file, copy the following text to a text file, and then save the text file by using a ".bat" file name extension. (The following example detects whether the operating system is 32-bit or 64-bit, and then it runs the appropriate command.)
  
  
   

  reg delete hkcr\typelib\{831FDD16-0C5C-11D2-A9FC-0000F8754DA1}\2.0 /f
  if exist %systemroot%\SysWOW64\cscript.exe goto 64 
  %systemroot%\system32\regsvr32 /u mscomctl.ocx
  %systemroot%\system32\regsvr32 mscomctl.ocx
  exit
  
  :64 
  %systemroot%\sysWOW64\regsvr32 /u mscomctl.ocx
  %systemroot%\sysWOW64\regsvr32 mscomctl.ocx
  exit
  

  To run the regsvr32 commands silently, add a /s switch to each of the regsvr32 commands in the previous example. For example:

  %systemroot%\system32\regsvr32 /u mscomctl.ocx /s
  

  
  Note You must run the batch file as an administrator:
  
   
  • To do this in Windows Vista, Windows Server 2008, Windows 7, or Windows Server 2008 R2, right-click the batch file, and then click Run as administrator.
  • To do this in Windows XP or Windows Server 2003, press and hold the Shift key, right-click the batch file, and then click Run as administrator.
