Read Me File for Patching the Image Processing Function Pack

This folder contains a patch program to update a program file for the Image Processing Function Pack, an add-on product for Mathcad. If you previously purchased the Image Processing Function Pack, you must apply this patch for your image processing functions to calculate correctly in Mathcad 7 Professional.

The patch program modifies the single file IMPROC.DLL, which by default was placed in the EFI folder of your Mathcad installation directory when you installed the Image Processing Function Pack. 

The instructions that follow assume that your IMPROC.DLL file is located in the C:\WINMCAD\EFI folder, but you should substitute the actual path to your Mathcad EFI folder. The instructions also assume that the patch program resides in the D:\FPACK folder; again, substitute the actual name of your CD ROM drive for D.

Running the Patch Program

To patch the file IMPROC.DLL, do the following: 

•	Close Mathcad if you currently have it open. 
•	Open a DOS Prompt window in your version of Windows. 
•	Type the following line at the command prompt (substitute paths to the patch program and EFI folder on your system if they differ from those given): 

D:\FPACK\PATCH  C:\WINMCAD\EFI  D:\FPACK\IMPROC.RTP

Note: Since the patch program is a DOS executable, it will recognize only DOS-compatible file     and directory names: up to 8 characters with up to a 3 character extension. 

When the program terminates, you may exit the DOS Prompt to return to Windows. Your file IMPROC.DLL is now patched to work with Mathcad 7 Professional. The new size of the file IMPROC.DLL should be approximately 481K bytes and be dated 6/97.
