I tried "Clean and fix my computer" and there is still a path problem. Here two examples:
HKUS\S-1-5-21-3832654586-1965245742-3141426226-1000\Software\Microsoft\Installer\Products\B743BCD27DDBCF04F8ED0C697596A8E2\SourceList\ : LastUsedSource 80 File or directory "C:\Users\Thomas\AppData\Roaming\FameRing\Smart Cutter 1" does not exist
"Open in RegEdit" shows this: n;1;C:\Users\Thomas\AppData\Roaming\FameRing\Smart Cutter 1.8.8\install\
"Explorer" shows the current path:c:\Users\Thomas\AppData\Roaming\FameRing\Smart Cutter\
or
