You can manual register the components.For this follow below steps..Example for xml regitration
1. Open notepad
2. type
regsvr32 /s %SystemRoot%\system32\msxml.dll
regsvr32 /s %SystemRoot%\system32\msxml2.dll
regsvr32 /s %SystemRoot%\system32\msxml3.dll
regsvr32 /s %SystemRoot%\system32\msxml4.dll
regsvr32 /s %SystemRoot%\system32\msxml6.dll
3. save the file as "myname.bat"
4. Double click file
5. All xmls registered
Same way you can register other components
** instead of double clicking the batch file you can use system.run command to automate
** i used /s to register it silently -- this way you will not see black dos screen popup
Thank You
