We have upgraded from IPP 5.1 to 6.02. We also want to be compatible with Windows Vista or Windows 7. This means system32 is "off limits" as an install location for the IPP DLLs. We also don't like the PATH environment solution, since anyone can change the PATH and break the DLL search algorithm. Why doesn't the "waterfall" procedure look in the current directory? This would solve our run-time problem of missing DLLs. Please advise.
