1. Click on the Windows Start button. In Windows XP, click on 'Run,' then type 'cmd' and click the 'Go' button. This will bring up the DOS command window. Vista and Windows 7 users click on Windows Start, then 'All Programs' followed by 'Accessories' and 'Command Prompt.'
2. Type 'regsvr32 vbscript.dll' and press the 'Enter' key.

3. You should now see the message 'DllRegisterServer in vbscript.dll succeeded.' If this message appears, the required files for the installer have been successfully registered and you should be able to install your programs.
4. Click on the installer file for your application and see if the error appears again. If the installation begins, the files are now properly registered. Repeat the process one more time if the installation still gives the 'Error 2753' message.
