- ==========
-
- This document discusses installation and configuration issues
- involved when both Borland C++ 5.0 and Borland C++ 4.52 are
- run on the same system.
-
- Borland does not recommend installing both versions 5.0 and 4.52
- on the same system. However, you can do it when absolutely necessary.
- Be forewarned that you cannot safely run both 5.0 and 4.52
- simultaneously at the same time. The problem with doing so
- is that the paths required by each product differ. To run either
- compiler version, you'll need to verify the path prior to invocation.
- The path must point to the appropriate \BIN directory
- of the version that you plan to use during the session.
-
- The procedure of changing the path and rebooting to switch
- compiler versions is a workable solution, but it may cause some confusion
- due to resulting file associations.
-
- For example, if you boot a Windows 95 system with both versions installed,
- clicking on the source code icon in the Windows Explorer will invoke
- BC5.0 even if the path specifies BC4.52. Being Windows 95 compliant,
- BC5.0 is entered into the registry whereas BC4.52, being released prior
- to Windows95, will not appear in the registry. BC5.0 will start, but will
- function poorly because the path points back to BC4.52.
-
- WARNING:
- It is easy to boot versions of BC from the incorrect path when switching
- paths frequently. This may cause error messages to occur that you may not
- immediately identify as being related to path problems. Failing
- to reboot after changing the path can cause similar problems.
-
- To change the path under Windows NT, use Control Panel | System | User
- Environment Variables.
-
- In Windows 95, you change paths by editing the AUTOEXEC.BAT file located
- in the root directory of the hard drive. However, repeatedly altering
- AUTOEXEC.BAT increases the possibility of error due to typographic
- and other errors.
-
- Because of the effort involved in changing paths on either
- platform, it is reccommended that a dual
- boot configuration be used on any system running both versions. Please
- consult the Windows 95 or NT documentation for information
- about adding dual boot capabilities to a system.
