I cannot create a new VCL application (Menu does not show any option) and that applications that already exists dont show any TForm descendent, but I can compile and it runs fine. Any clue?

  1. Check the registry for the delphivclide190.bpl located in HKCU\Software\Embarcadero\BDS\12.0\Known IDE Packages\Delphi. Make sure it is not mentioned in the Disabled Packages key. As a last ressort export and then delete the complete 12.0 subtree. It will be rebuilt with the next IDE start. However, you will have to re-install all third party packages.

  2. From https://bitbucket.org/jeroenp/besharp.net/src/default/Native/Delphi/Scripts/ download List-Delphi-Installed-Packages.ps1 run it from PowerShell and check the result to a machine that does work.
