Galapo i like to help, but what am i to do with that information?
Search your scripts for a mysterious bug?
I gave the links to the scripts in case you wanted to take a look at the unusual behaviour.
In any case, here's the relevant entries for IZArc:
Hive_Load,HKU
reg_add,0x2,"%reg%\Microsoft\Windows\CurrentVersion\App Paths\IZArc","","x:\%ProgDir%\%ProgramFolder%\IZArc.exe"
Hive_Unload,HKU
Hive_Load,HKCU
reg_add,0x2,"%reg%\Software\IZSoftware\IZArc","AppCurrentDir","x:\%ProgDir%\%ProgramFolder%"
reg_add,0x2,"%reg%\Software\IZSoftware\IZArc","AppTempFolder","x:\%ProgDir%\%ProgramFolder%"
Hive_Unload,HKCU
and UltraISO:
Hive_Load,HKLM
reg_add,0x2,"%reg%\ControlSet001\Services\ISODrive","ImagePath","\??\x:\%ProgDir%\%ProgramFolder%\drivers\ISODrive.sys"
Hive_Unload,HKLM
Hive_Load,HKU
reg_add,0x2,"%reg%\EasyBoot Systems\UltraISO\5.0","","x:\%ProgDir%\%ProgramFolder%"
reg_add,0x2,"%reg%\EasyBoot Systems\UltraISO\5.0","Shared","x:\%ProgDir%\%ProgramFolder%\Common"
Hive_Unload,HKU
Hive_Load,HKCU
reg_add,0x2,"%reg%\Software\EasyBoot Systems\UltraISO\5.0","","x:\%ProgDir%\%ProgramFolder%"
reg_add,0x2,"%reg%\Software\EasyBoot Systems\UltraISO\5.0","Shared","x:\%ProgDir%\%ProgramFolder%\Common"
Hive_Unload,HKCU
