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.

    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?
