Problem installing UFT 12.53 - "Failed to download and install Microsoft Script Debugger"

Hello,

Twice I tried to install UFT 12.53 and both times this error "Failed to download and install Microsoft Script Debugger:

 

http://download.microsoft.com/download/7/7/d/77d8df05-6fbc-4718-a319-be14317a6811/scd10en.exe. Please check log file for more information."

Where do I find this log file?

Is Microsoft Script Debugger really needed by UFT?  Is the file really big that it cannot be included in the UFT install package?

Is there any work-around to this problem?

Thanks.

Gilbert
