Trying to install 16th Sept 2025 release of vcl onto Delphi 7

[howshore]

I have the enterprise edition of Delphi 7. I downloaded JCL 2.8 Build 9330 and JVCL3.50 dated 16th September 2025. When I run the jcl/install.bat in an Administrator command prompt window I get:

dcc32 is available in my path because if I type dcc32 I get:

I tried editing the install.bat file to remove calls to build\dcc32ex and replace them with calls to dcc32 and it almost works except that the flags --runtime-package-rtl and --runtime-package-vcl aren't recognised by dcc32.
I don't understand the line "SET DELPHIVERSION=%1" in the batch file. The installation instructions say nothing about parameters on the "install" command line. I tried "install d7", "install delphi7" "install 150" and "install 15.0" but always I get "No Delphi/BCB/BDS version installed."

I assume dcc32ex is looking for a registry entry or a path variable or something to choose the version of Delphi to select. This appears to be missing in my environment. What can I do?

I am a little concerned that in the page "https://github.com/project-jedi/jcl" there is the text:

I hope "ddc32" is a typo and should be "dcc32" !

Here is the process that I use when installing a Delphi version:

Use the Delphi installer to the end, do not start the IDE
Reboot so that the PATH environment variable is updated
Start the Delphi IDE once, so that it's HKCU registry keys are created
Start the JCL install.bat script

With this, it works.

Now, if it tells you that it's still not finding any Delphi installation, it could be because dcc32 is missing, but then again, this is NOT the case with a genuine Enterprise installation, only with the demo versions.

Thanks for getting back to me, but I'm not certain what you mean by...

Use the Delphi installer to the end, do not start the IDE
Reboot so that the PATH environment variable is updated
Start the Delphi IDE once, so that it's HKCU registry keys are created

What do you mean by Delphi installer? I doubt if I could find my original Delphi7 CD.

I've had this PC since 2012, installed Windows 10 in 2019 and installed Delphi7 in 2020. I installed JCL in 2020 and I have used it for loads of software. I thought I'd update it to the latest (September 2025) last week. Obviously a bad idea. Of course I removed the old JCL before trying to install the new one so now I have nothing. I do have my original download so if all else fails I could try putting the old one back in.

I promise that dcc32 is not missing. How does dcc32ex work?

Could you upload all the values of this registry key: HKCU&HKLM\Software\Borland\Delphi?

[howshore]

I don't have a key for HKEY_LOCAL_MACHINE>SOFTWARE>Borland. I have attached the .REG file for HKEY_CURRENT_USER>SOFTWARE>Borland>Delphi
HKCU_Software_Borland_Delphi.zip

[howshore]

For your information I have also found HKEY_LOCAL_MACHINE>SOFTWARE>WOW6432Node>Borland>Delphi
HKLM_SOFTWARE_WOW6432Node_Borland_Delphi.zip
and
HKEY_USERS>S-1-5-21-1039213671-3145026187-2251707149-1001>SOFTWARE>Borland>Delphi
HKEYUSERS_S-1-5-21-1039213671-3145026187-2251707149-1001_SOFTWARE_Borland_Delphi.zip

Hope this all helps.

The issue is that RootDir is null/empty here. It should be "RootDir"="E:\\Programs\\Borland\\Delphi7"

[howshore]

I have made the change to the registry and will try the install again. Should I copy LMKEY and LMLIC from HKEY_CURRENT_USER>SOFTWARE>Borland>Delphi>7.0 as well?

[Delphier]

Just changing RootDir alone will do.

Thanks. I'm at work so I'll try this evening and get back to you. If it all works I'll mark your response as an answer. Thanks so much for all your help, and such quick response.

I have tried the solution suggested by Delphier and everything has worked perfectly. Thank you so much for such rapid support.
