1) Does anybody know the correct switchs for Jasc Paint Shop Pro 8.1. I tried several switch combinations including /qn, nothing seems to work? What happens is the next application starts to load before Jasc is finished loading. Jasc Photo Album also doesn't finish loading before the next app starts.

REG ADD %KEY%\051 /VE /D "Jasc Paint Shop Pro 8.1" /f
REG ADD %KEY%\051 /V 1 /D "%CDROM%\Software\PaintShopPro\psp810ensetup.exe /s /v/qn" /f

REG ADD %KEY%\052 /VE /D "Jasc Photo Album 4.0.3" /f
REG ADD %KEY%\052 /V 1 /D "%CDROM%\Software\Photo_Album\pspa403ensetup.exe /s /v/qn" /f

2) Does %CDROM% need to be changed to %DVDROM% for a DVD?

2) No, CDROM is just an environment variable you created with IF EXIST, it can be named anything really.

You could have it like this if you wanted to: IF EXIST D:\CDPath.txt set SOMEOTHERNAME=D:

and the environment variable pointing to where it located the file "CDpath.txt" will be called %SOMEOTHERNAME%

Thanks Aaronxp

In Case anyone wants to know! Extract the msi file /qn
