Question:
I tried to uninstall CBuilder 3 through Add/Remove 
programs, and I got an error (for example, 'Log file is 
corrupt'). 

How do I uninstall it from my system?

Answer:
There are three steps that you should go through in 
order to manually remove Builder from your computer. 

First, you should remove the registry keys, then you 
should remove the reference from the path statement and 
last you should delete the files. 


1)  Remove the Registry Keys
-------------------------------------------------------

The first part of actually removing C++ Builder 3 is to 
remove the registry Keys that the install places on 
your system.  The install.txt gives a list of all the 
registry keys added to your system  (those keys are 
also listed below).  

--------
WARNING:
Changing your registry makes changes that affect your 
whole system.  You should back up your registry before 
making any changes to it.  Inprise is not responsible 
for changes made to your registry.
--------

Before you begin editing your registry, make 
floppy-based backups of the Registry files. That way, 
if a problem occurs you have a safe backup. Don't use 
BACKUP.EXE but simply copy the following 4 files:      
system.dat
system.da0
user.dat
user.da0


To remove these keys, you first have to go into your 
registry.  Do this by going to Start | Run.  Type 
'regedit' at the prompt.  This will show you a list of 
registry keys, that looks a lot like a list of 
directories in explorer.  You can navigate this the same
way you would navigate through directories.

--------
WARNING:  Some of these keys may have been put on your 
system by other programs.  If you have other Borland 
Compilers, or other products that use the Borland 
Database Engine, remove only the keys specifically for
Builder 3:

SOFTWARE\Borland\C++Builder\3.0
--------

Go through the registry for the keys below, and delete 
them when you get to them.
 
A. File Extension Associations
  -----------------------------------------------------
  These are the file extension associations kept in the 
  registry under HKEY_CLASSES_ROOT:

  HKEY_CLASSES_ROOT\.bpg  = "BCBProjectGroup"
  HKEY_CLASSES_ROOT\.bpk  = "BCBPackage"
  HKEY_CLASSES_ROOT\.bpr  = "BCBProjectFile"


  B. Key Names added
  -----------------------------------------------------
  HKEY_CURRENT_USER
  Key Name: SOFTWARE\Borland\C++Builder\3.0
  Key Name: SOFTWARE\Borland\DBD

  HKEY_LOCAL_MACHINE
  Key Name: SOFTWARE\Borland\C++Builder\3.0
  Key Name: SOFTWARE\Borland\BLW32
  Key Name: SOFTWARE\Borland\Database Engine
  Key Name: SOFTWARE\Borland\Borland Shared



2)  Remove Builder 3 from the path statement
-------------------------------------------------------

Now you must remove Builder 3 from your system files.  

Note:  This document assumes that you have installed 
to the default directory.  If you have not, then 
instead of "C:\Program Files\Borland\CBuilder3\Bin", 
look for the path that points to the Cbuilder3\Bin 
directory on your system.

Windows 95
----------

Go to your start menu, and to run.  Type 'sysedit'.  A 
parent window with several child windows should open up.
The child window in front should say 'Autoexec.bat'.

In the Autoexec.bat, there should be at least one line 
that says:
path=
or 
set path=

Look through these lines.  Part of one of these lines 
should be the phrase:
C:\PROGRA~1\BORLAND\CBUILD~1\BIN;

From this line, remove 
"C:\Progra~1\Borland\Cbuild~1\bin;" (everything from 
the 'C' to the ';').

Now, Builder is out of your path statment.

Windows NT
----------

Right click on 'My Computer.'  You should see a property 
sheet titled 'System Properties.'  Click on the 
environment tab.

Within either your System Variables or your User 
Variables, you should have a Path variable that 
contains 

C:\Program Files\Borland\CBuilder3\Bin; 

Double click on that path so that it appears in the edit
box at the bottom of the tab.  Edit the path so that you
remove the entire reference to CBuilder3 (Everything 
from the 'C' to the ';').

Now, Builder is out of your path statement.


3)  Delete the Files
-------------------------------------------------------

Now you can delete the Builder files.  To delete those 
files, remove your entire CBuilder3 directory, and 
everything in it.  If you have no other Borland products
and know that you have no products that use the BDE, you
can remove the entire Borland directory.
