So is this the standard behaviour when it finds no dongle or so?

Some general hints would be to try a debugger-enabled build (-> sticky in the development forum) and see if it outputs something suspicious or boot DOS in DOSBox and install there.

Hello,
sorry for my late reply, but I was ill over the last week.

@wd
This application needs a dongle, but the behaviour is the same. The installer just drops back to the dos prompt.

Thanks for the ideas ... I'll try them and reply back as soon as I have any results.

Hello,
so I booted an MS-DOS 6.22 image, but I don't know how to access my hard drive or my floppy drive. Can anyone help ?

BTW: Before I tried dosbox I used VirtualBox and VirtualPC to run this application. Then the error message is "program too big to fit in memory".
What does this mean ? Is the installer corrupted or are EMX/XMS settings wrong ?

Usually "program too big to fit in memory" means a corrupted executable.

Hello,
I just tried running the installer on a PII 400 and didn't have any problems.
So the error message "program too big to fit in memory" doesn't necessarily mean that a program is corrupt.
I don't know what the problem with dosbox, Virtualbox or VirtualPC is.
I used the same boot disk I used with these programs to boot the PII 400 and everything worked out fine.
Thanks for all the help

Indeed, hard to tell.

Is the file you are executing on the boot disk whenever you tried it on DosBox/VirtualBox/VPC? Did you try copying the file to the HD for each emulator?

No, the installer file is not on the boot disk. It is on separate floppy disk.
I also made a disk image and mounted it in windows with a virtual floppy drive. But the behaviour is the same.
I don't think it makes much of a difference if the files are copied to the harddisk, but I can try.
