Can i create 64-bit setup using pure InstallScript?

Question

Can i create 64-bit setup.exe file using InstallScript project in InstallShield 2009? Documentation is only about msi projects. Or tell me alternative way to use 64-bit registry keys, please.

Answer 1

Technically, no, you cannot create a 64-bit InstallSciprt Setup.EXE. The Setup.EXE is a 32-bit application, but I don't think that's exactly what you were asking.

I think you were asking if you could author an InstallScript package that can run native 64-bit Registry/file system commands, and the answer to that is "yes".

For the Registry, which you specifically asked about, see: REGDB_OPTIONS

Add option REGDB_OPTION_WOW64_64KEY, and then you can call the Registry functions as you normally would, but they will operate on the 64-bit section of the Registry. To switch back to 32-bit, remove the REGDB_OPTION_WOW64_64KEY option.

Answer 2

When using REGDB_OPTION_WOW64_64KEY, be sure to always remove the setting before you leave your function as this can cause your setup.exe to not create an uninstall log in some versions of InstallShield; so while your setup.exe may run the uninstall it'll leave all of the files on the system because it does not create a Setup.ilg file

begin:

    if (SYSINFO.bIsWow64) then
 REGDB_OPTIONS = REGDB_OPTIONS | REGDB_OPTION_WOW64_64KEY;
endif;

end:

if (SYSINFO.bIsWow64) then
 REGDB_OPTIONS = REGDB_OPTION_USE_DEFAULT_OPTIONS;
endif;
