If double clicking on a *.txt file results in opening the file in UltraEdit, you have either associated the file extension TXT with Windows Explorer instead of UltraEdit and therefore have to change it also with Windows Explorer (Folder Options - File Types - TXT), or you have manually installed also the Notepad replacement tool which has the name notepad.exe
, but is not Notepad and instead starts UltraEdit. In second case you have to manually replace notepad.exe replacement by real notepad.exe of Windows XP whereever found in Windows directory and its (hidden system) subdirectories, see How to replace Notepad with UltraEdit?
UltraEdit v12.10a has not added much data to the registry in comparison to newer versions of UltraEdit using MSI and enhanced FTP/Telnet support (as UE v12.20 and later versions). Therefore it is quite easy to manually unregister UltraEdit v12.10a.For others reading the instructions below:
This manual uninstall is only for UE v12.10a. and does not work for later versions. UltraEdit v12.20 already adds much more keys to registry.
Start Notepad (or UltraEdit the last time), paste following lines into a new text file and save the file as UnInstUE1210.reg
. Then double click on this registry file and comfirm importing the data. The file does not add anything to registry, but instead deletes registry keys.
- Code: Select all
[-HKEY_CURRENT_USER\Software\IDM Computer Solutions]
[-HKEY_LOCAL_MACHINE\Software\IDM Computer Solutions]
Next run regedit.exe
and navigate to key HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\View Source Editor\Editor Name
in the tree. If the default string at top of right side contains uedit32.exe
, replace the value of the default string by C:\Windows\Notepad.exe
if Windows XP is installed in directory C:\Windows, otherwise use the correct path to Notepad.exe in Windows directory. Exit Regedit after this modification.
Now open Control Panel
, double click on System
(or press key combination left Win+Break) to open the system settings configuration dialog. Select tab Advanced
and click on button Environment Variables
. Look in both environment variables lists for variable PATH
. If one of them contains the UltraEdit program files directory, select variable PATH
, press button Edit
below the list and remove the UltraEdit program files directory with the semicolon at end. Press OK
several times to close the system settings configuration dialog.
You have to restart now Windows as the shell extension DLL of UltraEdit is still loaded by Windows Explorer although already unregistered and therefore can't be deleted. After restart of Windows
- delete the UltraEdit program files directory completely,
- copy %APPDATA% into address bar of Windows Explorer, hit key RETURN and delete the directory IDMComp completely,
- delete in start menu of Windows the UltraEdit group with the UltraEdit shortcuts if present,
- delete on desktop the UltraEdit shortcut(s) if present,
- delete in quick launch bar on Windows task bar the UltraEdit shortcut if present,
- delete in Windows directory all files starting with uedit32, all *.mfg, *.pfg and *.tfg in case the user customization files are in Windows directory instead of %APPDATA%\IDMComp\UltraEdit.
You are finished. UltraEdit is completely uninstalled including the user customization files and settings normally not removed by the uninstaller.
