One of my systems has a broken Delphi installation: it thinks BDSCOMMONDIR points to C:\Windows\system32\9.0 whereas on a functioning system, it points to C:\Users\Public\Documents\RAD Studio\9.0.

I’m probably the victim of corporate security madness, as I found out nobody can access the C:\Users\Public directory on the failing system anyway.

What I want is to move the content of the directory to a place where the developers can write, then globally (a subdirectory C:\ProgramData comes to mind) and globally set the BDSCOMMONDIR.

So: where does Delphi get the BDSCOMMONDIR value from?
How can I override it?

The major reason why it is holding me back is that I now get this on every compile/build I try:

[MakeDir Error] Unable to create directory "C:\Windows\system32\9.0\hpp\". Access to the path 'C:\Windows\system32\9.0\hpp\' is denied.
[MakeDir Error] Unable to create directory "C:\Windows\system32\9.0\Dcp". Access to the path 'C:\Windows\system32\9.0\Dcp' is denied.
[MakeDir Error] Unable to create directory "C:\Windows\system32\9.0\hpp". Access to the path 'C:\Windows\system32\9.0\hpp' is denied.

    You can go to

    Tools|Options|Environment Options|Environmental Variables

    double click on

    BDSCOMMONDIR

    and set it to whatever you want.

    Also get a look at Where are environment variables stored in registry?
