NOTE:  All programs listed below can be run by anyone who downloads them.  You do not need to be a purchaser to run any of them.  

General CADD programs will run in "Demo" mode if you have not yet purchased the program.  File Saving is disabled in Demo mode. 

VISTA, Windows 7 & 8 Users Please Note!!
You must have Administrator rights and “User Account Control” (UAC) must be turned OFF before installing. After verifying that the program has been installed, UAC may be turned back ON.  This setting is found in the “User Accounts” section of Control Panel.


Because of the many differences between previous versions, the full install will create a new parent folder C:\General Cadd 12.  All files pertaining to Version 12 will be kept in this directory structure.  This version will not overwrite or replace any existing version of GCP.

If you have older versions of GCP on your computer, you will have to copy any fonts, hatches, macros, drawings and components you wish to use with the Version 12 from the previous General Cadd installation folder.   In the V12 Help Drop Down Menu is a MIGRATE Environment command which will assist you in copying your files.
