--- Comment #12 from Michael Karcher wine@mkarcher.dialup.fu-berlin.de 2011-05-30 10:59:46 CDT --- What do you mean by "doesn't work unless I use native jscript"? I tried "msiexec /i winetest.msi" on a clean prefix, and the license code "VALID" will be rejected, as well as after installing wsh56js via some (outdated) winetricks version and setting jscript to (native,builtin).
Did you manage to get "VALID" accepted (i.e. the installer exiting) with builtin msi and native jscript?
