Do not install Borland C++ 4.5 over previously installed Borland C++ directories from versions 4.5 or earlier. The files in this distribution will not work with previously shipped tools and libraries. This is particularly true for configuration files from previous shipping releases, like TDCONFIG.TDW and BCCONFIG.BCW. If you used Turbo Assembler 4.0 or the Borland Power Pack for DOS with a previous installation of Borland C++, you must reinstall those products after installing Borland C++ 4.5. If you used CodeGuard for Borland C++ 4.5 with a previous installation of Borland C++, you must reinstall CodeGuard after installing Borland C++ 4.5. Also, be especially careful when using object files and libraries from earlier Borland C++ versions with binaries created with this release. There are several potential problems when linking with old objects or libraries. Exceptions won't work correctly (destructors won't get called) when a pre-BC4 stack frame is unwound due to an exception. Do not use long file names when installing under Windows NT. ----------------------------------------------- Installing Borland C++ 4.5 on your hard disk ----------------------------------------------- For information about installing Borland C++ 4.5 from CD-ROM, see the CD booklet. To install Borland C++ 4.5 from floppy disks, 1. Put disk 1 in your floppy drive. 2. In Program Manager, choose File|Run. 3. Type A:\INSTALL. (If your disk drive is not drive A, type the appropriate letter instead.) 4. Choose OK. 5. Follow the instructions on the screen. Diagnostic and debug version of OWL are not installed to the hard disk, but they can be copied from the CD or built from OWL source using the makefile provided. Users of ObjectWindows 1.0, Turbo Vision 1.0, or the Paradox Engine should read the COMPAT.TXT file for information on using these products with Borland C++ 4.5. To get Turbo Profiler, you must install the debuggers. **** Note to Windows NT, OS/2, and Windows 95 users **** If you intend to use Borland C++ under any of these platforms you must follow some additional installation steps, which are listed in the INSTALL.TXT file. If you fail to read and follow these configuration guidelines, you may encounter several significant problems when using Borland C++. The following files which appear in the BC45\BIN directory are intended for Windows 3.1 and may not work correctly in conjuction with 32-bit applications running under Windows 95: DIB.DRV YESMOUSE.DRV VGAP.DRV MSMOUSE.DRV However, certain 16-bit applications require these drivers to run. For more information about installing and configuring Borland C++, see the file INSTALL.TXT which can be found in the following locations: * Borland C++ floppy disk 1 (INSTALL.TXT) * Borland C++ CD-ROM (\BC45\INSTALL.TXT) *************** 3. NEW FEATURES *************** Borland C++ 4.5 is an update to 4.0. The main difference is the upgrading of header files and import libraries to support the Windows 95 programming. There is a new version of the OWL libraries (2.52) to accommodate some altered structure definitions in the new Win32 headers. In addition, 4.5 makes small improvements to our VBX support.
