I have a build machine that has multiple versions of InstallShiled installed on it - because we have multiple versions of our software utilizing different versions of IS. Right now we have IS 11.5 and 12. Later we'll add 2008.
Because the version of IsCmdBld.exe that FB uses is specified under the Options menu/ InstallBuilders, if I want to use the built in InstallShield action (MSI) in my scripts, I cannot have two different scripts or actions building two .isms from different versions of InstallShield.
Could there be a way to supply the version of IsCmdBld.exe in the build InstallShield...(MSI) action itself? That way the same action could be used for different versions of IsCmdBld.
Thanks,
Jason

You should be able to change the installer version at runtime with script, somethnig like:
dim ISOptions
set ISOptions=GetOptionsObject(“InstallShield”)
set ISOptions.CompilerLocation=“c:\program files\InstallShield 6”
or whatever.
See “Accessing the Options settings via script” in the help file.
