Delphi became unregistered when I upgraded to Windows 7

Question

I've been using DELPHI 6 with Vista very successfully, however, after upgrading to Windows 7 my Delphi 6 is no longer registered. Even after successfully registering it on-line, it will not save it, and as such, never gets registered. How can I register it?

Answer 1

The same problem on Win 10 is solved:

1. In register HKEYCU->SOFTWARE->BORLAND->6.0 delete row LM (REG_BINARY)
2. Save
3. Run register form of Delphi with Embarcadero account

Now Delphi 6 should be registered and work ok.

Answer 2

A couple of possible solutions:

• Use the Windows XP mode feature of Windows 7 to run Delphi 6.
• Run Delphi 6 as Administrator using elevated privileges (for instance by using this trick).
• Run Delphi 6 in a VM (actually: Windows XP mode is a VM too)
