How do I manually uninstall Delphi?
Answer:
When uninstalling a program it is best to use the utility
Add/Remove Programs found in the Control Panel in Windows,
but sometimes this does not work properly. Here is a guide
to help you uninstall Delphi manually.
There are four major areas where you will need to delete:
The Delphi directory, the Borland Shared directory, the
System32 directory and the Windows Registry.
1. The Delphi directory is easy. Just go into Windows
Explorer and delete the entire directory called Delphi5.
This should be under the directories Program Files\Borland.
2. The Borland Shared directory has more then one possible
location but the most common is Program Files\Common
Files\Borland Shared. If you are removing all Borland
software that uses the BDE from your machine (i.e. Delphi
and C++ Builder) you may be able to just delete the entire
directory. Be aware that there may be other programs that
use the BDE such as Corel paradox. It may be a good idea to
always leave the BDE directory unless you are certain.
3. The System32 directory is located in your operating
system directory, for example WINNT\System32. It will be the
trickiest because it contains many files and only a portion
of them are used by Delphi. The key here is to look on your
Delphi CD for the System32 directory to find which files to
delete. The files contained under the Runimage directory on
the CD are in more or less the same directory structure as
they are on your machine. The main exception is that the
Windows\System32 directory located under Runimage\Delphi50\
on the CD contains items that are actually contained in the
OS directory on your machine.
One tip is that Delphi files of the same version have the
same date and time, so if you go into the System32 directory
and sort by 'Modified' you should be able to group all the
Delphi files together so you can delete them all at once.
4. In order to make changes to the registry you must open to
utility regedit.exe. Go to the Start menu and select run,
then type 'regedit'. Once in the registry open the entry
HKEY_LOCAL_MACHINE\SOFTWARE\Borland\Delphi. Right click on
the version of Delphi you are deleting such as 5.0 and
select delete. If desired remove other directories under
here as well. Now you should simply do a search on the
registry for 'delphi' and 'borland' and make your own
judgment as to whether there are other entries you want to
delete.
One final step you may want to take is to remove all the
file extension associations with Delphi. If you did a search
on the registry in step four then you may have already done
this. It can be done by opening Windows Explorer and going
to the menu View | Options. The extensions associated with
Delphi 5 are: dfm, dpr, dpk and pas.
