Please update to the latest update 46.1.827 in the normal way (be aware it will pause on the black screen and then do reboot due to some system maintenance in this update)
827 fixes a bug that I found as I was about to explain the below.
then:
Either:
1. Got to the Back and Restore Section:
Choose Restore Systemv46 Partition in the Restore To Inbuilt Defaults section.
Click on the blue "Restore To Inbuilt Defaults" button that then enables.
From the choices you are then offered choose "Replace"
Once this has completed, goto the AmiSphere panel and choose the Advance Update button
Here just choose system.lhapps
and then Install selected archives.
You should be good to go with a reset latest AmiBench with YAM et al
2: If The Restore part above didn't offer to reinstall SystemV46.tar you may have a early image without archives, in this case.
From the Main A600GS Gui start DOpus4
In DOpus4 enter LIBS: on one of the directory panels
Select LIBS:MUI drawer and then press DELETE.
Then goto the AmiSphere panel and choose the Advance Update button
Here just choose system.lhapps
and then Install selected archives.
