*********************************************** READ ME FILE FOR MATHCAD PLUS 6.0 PATCH PROGRAM *********************************************** This patch program for Mathcad PLUS 6.0 will patch all English-language versions of Mathcad PLUS 6.0. This patch program will *not* patch foreign-language versions of Mathcad PLUS 6.0 (French, German, Japanese), nor will it patch any version of Mathcad 6.0 Standard Edition or Mathcad 6.0 Student Edition. This patch program will patch existing versions of Mathcad PLUS 6.0 to level 6.0c. If your version of Mathcad PLUS is already at level 6.0c (determine this by seeing if the serial number on your startup screen ends in the letter "c"), this patch program will have no effect. To run the Mathcad 6.0 patch program, you will need to know where your Mathcad program files are located. By default these files are installed by the Mathcad installation program in the C:\WINMCAD directory. If you are unsure about where your Mathcad program files are located, search for the directory that contains the Mathcad program MCAD.EXE. If you have moved Mathcad program files to new directories after Mathcad installation, see the CUSTOM PATCH INSTRUCTIONS at the end of this file. NOTE: The patch program will not make any changes to any Mathcad MCD, PRN, DAT, or AVI files you have created. You may safely leave your working Mathcad files in any directories where the patch is taking place. STEP-BY-STEP INSTRUCTIONS 1. Open a DOS Prompt window in your version of Windows. 2. Type the following command at the command prompt: A:\PATCH C:\WINMCAD A:\MCAD.RTP Substitute in the command string the name of the directory where the patch program is located if it is not in A:\. Substitute a full path to your installation of Mathcad 6.0 if it is not located in the C:\WINMCAD directory. For example, if you have downloaded the patch program to the C:\MYSETUP directory and your copy of Mathcad is in the C:\MYMCAD directory, you should type C:\MYSETUP\PATCH C:\MYMCAD C:\MYSETUP\MCAD.RTP 3. The patch program will make changes to MCAD.EXE and several other Mathcad program files. When the program terminates, you may exit the DOS Prompt to return to Windows. 4. Launch Mathcad as you normally would. You will know that the patch has taken effect if you see the letter "c" after your serial number on the Mathcad start-up screen. If you have difficulty using the patch program, contact MathSoft Technical Support. In the U.S. and Canada, phone 970-339-7119 or 303-339-7119, or send e-mail to support@mathsoft.com. Elsewhere, contact your local support center, or send e-mail to help@mathsoft.com. *************************************************************** CUSTOM PATCH INSTRUCTIONS If you have moved Mathcad program files from their original installed locations, you may patch the program files individually. If you are able to patch your Mathcad files using the instructions above, however, you should not need to do this and may safely ignore all that follows. For example, if you want to patch the file FOO.BAR which is in the directory \FOODIR you type A:\PATCH /file:FOO.BAR \FOODIR A:\MCAD.RTP assuming that the program PATCH.EXE is located in A:\. The list of files to be patched is given in the file MCAD.RTD that accompanies these patch instructions. *************************************************************** Patch 6.0c March 1996
