I have been searching google all day for a fix for the 1606 error with no easy solutions found.
I have just completed your tweaking program but no luck here.
the articals on the web are conflicting as to the possible cause, one says it's Java, another says it's an Install Shield error. Microsoft admits to thousands of complaints but they simply refer to thier MrFixit program which is a joke.
OH, the error refers to a missing %PUBLIC%\. folder which install programs need.
There are lots of articals (yeah, bad spelling) on the web but I am not very literate so solutions must be very simple.
Any help would be very welcome.
