Do not attempt to capture the SAP GUI 7.20 installation with Wise Smartmonitor turned on. It causes the SAP GUI installation program to hang and you will get nowhere. Capturing can be completed with Wise Smartmonitor off.
Rather than trying to capture the raw install with the GUI and patch runs, it may be easier to utilise the SAP installation server software. This gives you the ability to create a package which can install silently, with the selected features and patch levels you require. This is a much easier propect to capture and if it all goes wrong and you need to start again you won't have to face a protracted install process during capture.
Other Notes
The capture needs a fair amout of cleaning up. A lot a COM registration infomation is not exclusively associated with the appropriate components and duplicated in large generic registry components.
A couple of ini files contained non-standard entries (don't they all?) so these were tranferred to file installs rather than inifile table contructs.
Even though office is a prerequisite capturing on a clean machine is probably preferrable here rather than one with office installed.
