A: Error 80000003
immediately after launching the installer is
usually caused by running Installer version
44.10 on a 68000 or 68010 CPU. Installer
44.10 requires a 68020 or higher CPU.
The issue can usually be solved by
replacing the 44.10 Installer software with
Installer version 43.3 (available
here). This is just one
file named "Installer", which by default is
inside the Utilities directory of the system
drive. To be viewed from the Workbench
desktop environment, it requires
"Window/Show All Files" to be selected, as
it does not have an accompanying Amiga icon
Both versions of the Installer software
are included in the Storage disk of the
Classic Support Workbench
3.1 disk set. The Workbench 3.1
installation script performs a CPU check and
installs version 43.3 (from the "Update"
directory) on systems with a 68000 or 68010
CPU or version 44.10 (from the
"Update-68020" directory) on systems with a
68020 or higher CPU. However, if the
destination media (e.g. a CompactFlash card)
is then used on a system with a lower CPU,
it may be necessary to manually "downgrade"
the Installer software.
