system variable PROGRAMFILES empty on Win2000

[JH]

Pardon a novice with a stupid question, but how will the IS compiler know
what MsiGetProperty() is?
Do I need to load a DLL? How can I be sure the DLL exists on the target
platform? And if it does not?

Thanks again for your help.

Looking back into the original question trail and this , I have to ask: what
product do you use?
InstallShield Express 3 (check-list wizard producing MSI) or InstallShield 3
(no longer supported script only based compiler)?

If you use IS 3: just call
RegDBGetKeyValueEx( HKEY_LOCAL_MACHINE,
"SOFTWARE\\Microsoft\\Windows\\CurrentVersion", "ProgramFilesDir", nType,
svWhereProgramFilesFolderIs, nSize);

If you use IS Express 3:

You have every right to ask such question, because documentation doesn't
give you a great deal of explanation here.
InstallShield Script compiler links to MSI API via

#include "iswi.h"

-which suppose to be in the default script generated for every new .rul
file.
MSI API functions are exported in MSI.dll, which is installed on the
end-user's machine if Windows Installer engine is available there.
So if your installation package is running - MSI.dll is there and the API
calls will work.

More details on function syntax can be found in MSI help library (from
InstallShield help menu)

Let me know which product do you use and sorry for confusion,
Alex Rodov

This did the trick:

RegDBSetDefaultRoot( REGISTRY_BASE_LOCAL );

DBGetKeyValueEx(

"SOFTWARE\\Microsoft\\Windows\\CurrentVersion",
"ProgramFilesDir",
nType,

ProgramFilesFolder,
nSize );

Thanks

REGISTRY_BASE_LOCAL is the same as HKEY_LOCAL_MACHINE
