Program crash after memory upgrade

[Guest]

I have to use a fairly old CAD program because I still need access to the old
drawings. No upgrades are avilable because the product line was abandoned by
the original producer. The program runs fine under Windows XP SP2 on my
ThinkPad R51 with 1Gb (single 1Gb bank) and 1.25Gb (1Gb+256Mb bank) memory.
When I upgrade to 2Gb it crashes at startup with a message box "Microsoft
Visual C++ Runtime Library" - "Run time Error". There are no entries in the
system event log.

Right now I have to take out the second 1Gb stick when I want to do CAD and
put it back in when I want to do photo editing, which is annoying and will
probably riun the socket soon.

I guess there is a problem with address space that the old software can
address. Is there any way in Windows XP to limit the amount of memory that an
application needs to manage? Are there any upgrades to the C++ Runtime
Library that could fix the problem?

Thanks for any help

Run a RAM test on *only* the new RAM...it's possibly defective or not
compatable

is this an old DOS program?

You should also indicate the old and new CAD programs you have; someone may
have a suggestion for converting from one to the other. CAD programs are
notorious for being able to move from app to app by conversion.

The original software that created the files was Blueprint for the Macintosh
(year 1995). Blueprint is gone, but Vectorworks 8.0.1. can read the files on
Windows. That version is what crashes now. Vectorworks is still around (now
version 12), but at least version 9 and up cannot read the files, even after
re-saving in various formats under version 8.0.1.

The new 2Gb memory is the type recommended by Kingston for this type
computer. All hardware checks show that both sticks are good. Lavalys-Everest
shows that both sticks are what the box claims they are (PC2700-166MHz etc).

I am fairly certain that the root problem is a limit in the address space
that some library routine can manage, so either the OS has to limit the
amount of memory that the program has to manage, or the library needs an
update. I don't know how to do either.
