Symptom(s):

I ran an Intel® IPP application and obtained one of the error messages below:

"No DLL was found in the Waterfall procedure."

"This application has failed to start because ippxx-x.x.dll was not found."

Cause:

Windows* is unable to determine the location of the Intel IPP dynamic libraries.

Solution:

Four solutions to this problem are listed below:

1. Before using the Intel IPP dynamic libraries, add the location of the DLLs to the PATH environment variable. The instructions below are for a Windows* XP system. Please refer to your operating system help file for more information on how to set environment variables.
   
   
   1. Open Control Panel and select System.
   2. Click Advanced.
   3. Click Environment Variables.
   4. Double-click the variable PATH in User Variables.
   5. Add the path to the Intel IPP dynamic libraries to variable value.
      For example, if you installed the Intel IPP to the default location and are running a 32-bit application then add C:\Program Files\Intel\IPP\x.x\ia32 to the PATH.
   6. Close all Control Panel windows.
   7. Close Microsoft Visual C++*.

   Note: Make sure to close Microsoft Visual C++ and restart to have the PATH variable take effect. Then rerun the application.

2. Use the Intel IPP Runtime Installer (RTI), located in IPP\x.x\ia32\tools\runtime, to automatically install the dynamic libraries to the \system32 directory.
   
   
3. Manually copy the contents of IPP\x.x\ia32\bin to the \system32 folder.
   
   
4. Copy contents of IPP\x.x\ia32\bin to the application folder.

Delete all Intel IPP DLLs from previous releases from the c:\winnt\system and c:\winnt\system32 directories. Also verify that paths to older library versions are not listed in the PATH environment variable.
