INSTALL-E-NOINST64B, cannot install images with 64-bit image sections

Hi, group,

I want to install an executable image /open/header/shared [/nowrite] to
conserve physical memory, because there are many of these images
executing in parallel.

However, this fails an OpenVMS Alpha 7.3-2 with the following error
messages. The same works on OpenVMS V8.2-1 on Itanium (I don't have
newer Alpha versions available).

Installing the image without all of the above qualifiers works, but
that's not what we need (sharing memory).

The problem seems to be (and the error message says it), that the
image contains data sections in the 64-bit address space (others
can be installed without problems).

Now the questions:
- is this VMS version dependent, or Alpha dependent?
- if version dependent, from which version on can it be done?
- are there workarounds, patches available to enable this on V7.3-2?

Can anybody, please, shed some light on this?

Here are the failing statements and some more info:

This fails:

$ inst add XXXX:[TEST1]TEST1 /shared
%INSTALL-E-FAIL, failed to CREATE entry for DKC301:<XXXX.TEST1>TEST1.EXE
-INSTALL-E-NOINST64B, cannot install images with 64-bit image sections

This works:

$ inst add XXXX:[TEST1]TEST1
$ inst list/glob/full TEST1:[TEST1]TEST1

DKC301:<TEST1.TEST1>.EXE
TEST1;1

This is the VMS version:

Thanks for help and/or clearing this up
