Can Delphi 6 be installed in Windows 10

Question

Previously, a few weeks back,
I asked a similar question regarding D6 and Windows 7.
After installing Delphi 6 in another path, it worked.

BUT now,
after upgrading from W7 to Windows 10 it no longer works.

I am prompted to register the software.
I do that, and am told the registration was successful.
Attempting to start again I am told license information
is invalid or missing.

The program will not start.

What is needed to run D6 in a Windows 10 machine?

I just install it to its default location and apply a permissive ACL on C:\Program Files (x86)\Borland\Delphi6 – Vinculum

Answer 1

There is an Howto I've found at ViaSoftThink I've translated it for you

How to: Don’t install under C:\Programme (x86) use another folder e.g. C:\software_old

After the installation you're forced to register. Whether the registration process was canceled or successful you probably get an error message:

"License information is invalid or missing Please register"

Now do the following:

Execute c:\software_old\Borland\Delphi6\bin\D6RegClean.exe

After this install Delphi 6 from your CD but this time choose "repair"

To use the Help System you need to install WinHlp32.exe Microsoft doesn’t give you an Installation Package but you can download it here

If you follow the steps above and still have a registration error pop up there might be that you need to edit the registry at:

HKEY_CURRENT_USER\SOFTWARE\Borland\Delphi\6.0

On the right side you'll find an entry which is called LM Delete that key and try again registering...

Please note: Messing around with the registry can break your system only do it if you know what your doing

I deleted LM, and it worked. No D6RegClean, no repair. – Zane

No problem its a pleasure – Vashtee

Yep, just delete the LM key, none of the rest of this answer is necessary. – Aristotelian

Answer 2

Deletion of LM key, worked for me,

1. Delete key.
2. Reboot.
3. Launch Delphi, choose register later, quit.
4. Launch Delphi again, works OK.

Also, I modified authorization of c:/programmes/borland/delphi/bin to total control and delphi32.exe compatibility properties to Windows XP and executed as administrator.

Answer 3

Restart Delphi and choose register later. New LM key will be created and you can continue unregistered Needed to fix legacy code from 2005
