Internal error 2738" appears during installation of Corel 12 to Windows7 x64

Good morning. I have tried to install Corel 12 to Windows 7 (x64) and I have meet problem that I was not able to resolve.  Corel 12 refuses to install himself reporting "Internal Error 2738". I tried to solve this problem by re-registering vbscript (recommended for Windows Vista), but with no effect. Would anybody be so kind to help me? Thanks.
