Cannot start Delphi

[Skrim 11]

When I try to start Delphi (12.2) I get an error,

 

List index out of bounds (6) TList range is 0..5

 

When I click OK the program closes. I have tried to reinstall, but did not help.

 

Any ideas?

I have decided to do a complete clean reinstall.

 

No wonder things fail from time to time, 2068 Registry keys were leftover from the uninstall

If you have thirdy parts component installed try to delete them.

 

If this don't help, you can try to do a clean install.

 

After you have disinstalled RAD STUDIO !!!, do those steps:

 

1) Delete the Windows registry (and all subfolders of course):

• HKEY_CURRENT_USER\Software\Embarcadero
• HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Embarcadero

2) Delete the folders (and subfolders) of your disk (YOURACCOUNTNAME is the name of your account):

• C:\Program Files (x86)\Embarcadero
• C:\Users\YOURACCOUNTNAME\AppData\LocalEmbarcadero
• C:\Users\YOURACCOUNTNAME\AppData\Roaming\Embarcadero
• C:\Users\Public\Documents\Embarcadero\Studio\23.0\Bpl
• C:\Users\Public\Documents\Embarcadero\Studio\23.0\Dcp
• C:\ProgramData\Embarcadero

Take care about you are doing.
