"not a valid win32 application

I have MatLab 5.2 which quite happily runs an old pre win32 dll running on Windows XP. However when using MatLab R2007b it states that the dll is 'not a valid win32 application'. I do not have the source code for this old dll so cannot recompile it; is there a work around for this problem?

A similar problem was discussed in a previous question. Is your MATLAB a 64-bit installation? If yes, you cannot call into a 32-bit DLL. You can however install 32-bit MATLAB on your 64-bit machine to be able to call into the 32-bit DLL. See here for installation instructions and here for some caveats.

Like I explained before - it is likely that you have the 64-bit version of MATLAB for R2007b (the first version of 64-bit MATLAB was R14SP3) and 32-bit MATLAB for the older version.
