Manual Uninstall Delphi

In some cases you need to uninstall your Delphi license. For example due to a conflict with an expired trial or beta version.
You will find the steps for a manual uninstall below.

Manual uninstall of RAD Studio/Delphi/C++Builder 12.0 Athens

Launch the License Manager from the bin folder (by default “C:\Program Files (x86)\Embarcadero\Studio\22.0\bin\LicenseManager.exe”) and delete any trial or beta (Test Field) license that you can find. Check it under “License Details” in the center column.

Under your Control Panel’s Program and Features Add/Remove Program uninstall the following entries:

RAD Studio 12 version 23.0

Please follow these instructions to remove any leftover files:

1. If Windows 64-bit, remove the C:\Program Files (x86)\Embarcadero\Studio\23.0 directory (or the custom folder you had used).
2. Remove the C:\Users\Public\Documents\Embarcadero\Studio\23.0 directory
3. Remove the C:\ProgramData\Embarcadero\Studio\23.0 directory.
4. Remove the %APPDATA%\Embarcadero\BDS\23.0 directory.
5. Remove the HKEY_CURRENT_USER\SOFTWARE\Embarcadero\BDS\23.0 registry key
6. If Windows 64-bit, remove the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Embarcadero\BDS\23.0
7. If Windows 64-bit, remove the following files from C:\Windows\SysWOW64:
BDEAdmin.*
CC32*.DLL
