I have read about the infamous VSTA error and 1603 error during installation.  I am also receiving this error message when installing the 64-bit edition on Windows 7.

I am logged into my computer with administrative privileges.  I have also tried right-click "Run as Administrator..." on setup.exe

I tried uninstalling Microsoft Visual Studio 2005 for Applications.

NOTE: I was not able to find any key in the registry called HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\VSTAHost

I have tried manually installing Microsoft Visual Studio 2005 for Applications from the PreReqs folder.

All to no avail.  I have attached the installation log file.

Please help!
