On moving to windows7 I could not get Delphi6 to install. I found the solution to be not installing under Program Files (I installed in c:\Delphi). My problem is that now when I try to add a new item to my project (a dialog for instance) I get a message saying that the files cannot be found. I think it may be something to do with registry entries for Objrepos but I am not confident enough to go editing the registry.

  • You can easily install under Program Files. My Delphi 6 lives there. Just put a permissive ACL on the Delphi6 folder under program file \ borland – David Heffernan Dec 20 '14 at 12:54
  • Delphi also works fine installed outside the Program Files folder. I have all my copies of older Delphi installed under *C:\Delphi*, and all my newer versions installed under *C:\RAD Studio*, and they all work fine (including the Object Repository items). – Ken White Dec 20 '14 at 15:40

As you say, this sounds like a broken installation.

The Delphi installer in older version could be sensitive to certain thing. For example, installing update, components or IDE add-ons before having first started the IDE (the registry could become messed up), or attempting a re-install over the top of a previously failed install (previous, invalid registry settings not properly over-written).

Rather than attempting to fix whatever installation issues have been caused, it may be simpler to simply eliminate these possible causes by doing a complete uninstall of the affected version, and re-install from scratch.

Whether you choose to install under Program Files with permissions changes, or under a separate folder, outside of Program Files (a personal preference - I myself favour the latter), be sure to start (and shutdown) the IDE at least once immediately upon completing the initial installation, to ensure initial registry settings are intact, before installing any updates, additional components or add-ons (such as GExperts etc).

  • Thanks Deltics - that solved the problem on my home machine where I had previously tried to do the default install and obviously the registry entries had not been set correctly. I will now ask the IT guys at work to do the same on my machine here although I am surprised it happened here as I asked them to install outside Program Files - perhaps they also tried the default installation first.
