friendlyway composer 7

I have the following error during composer 7 installation: “The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2738.” How can I solve this problem? This problem can be solved through the re-registering VBScript.dll. Here are the steps:
1.    Run a command prompt in administrator mode (go to Start>All Programs>Accessories, right click on Command Prompt, and select Run As Administrator).
2.    Type in: cd C:\Windows\System32 (replace the directory if it’s different for you).
3.    Type in: regsvr32 vbscript.dll.
After that, a message about successful registration will appear.
