really be the problem?!?!
What makes you think the file got copied properly to the different computer?
By the way, I've looked at the code, and it doesn't appear to be worth the
trouble to replace that %1, because dyn.load() is platform-neutral, while the
message only has that format in Windows. The full error message (which it
would have helped if you'd shown) is something like:
unable to load shared object 'D:/stuff/junk.dll':
LoadLibrary failure: %1 is not a valid Win32 application.
The %1 is just the file listed on the previous line.
Usually Microsoft gives more information in a popup. But we cannot be
held responsible for Microsoft's arcane error messages. Note that
they give that message not only if junk.dll cannot be loaded, but also
if some DLL on which junk.dll depends cannot be loaded. As I said, in
XP or later (but not 2000) there should be a popup message box with
the details.
It this works on 32-bit R on one computer and not another, the most
likely explanation is that a dependent DLL is missing. We recommend
'Dependency Walker' (www.dependencywalker.com) for a GUI-based program
to examine such issues.

Okay, I get the error message you showed if I try to load something
that really isn't a valid Win32 dll, and I don't get it when I load
a valid one. (I'm not sure if I can fix it to replace the %1 with
the filename; I'll look into that.) How do you know your dbsvls.dll
really is valid?

Hi Everyone,
I am trying to work with a routine that is from the IMSL
called
BSVLS. I
have the file as a .dll file.
I have been trying to call the routine using the dyn.load
function. I am
working on a 32-bit windows 7 OS with 3 GB. For some
reason i
still keep
getting the error message
LoadLibrary %1 is not a valid Win32 application
I looked at previous posting and they were all related
to people
trying to
run dll files that was created under 64bit and not under
32bit.
But I am
running it on the correct settings.
I have placed the .dll file in the BIN folder so R can
find it.
Any thoughts? ideas on how I should handle this?
Why don't you tell us what you did?
