property passed on setup.exe command line not available during install
I have a basic msi. I have added a text box to the InstallWelcome dialog with the text field set as MYPROP=[MYPROP]. I run the following command: setup.exe /v"MYPROP=abc" When the InstallWelcome dialog is displayed, I see MYPROP= I would expect to see MYPROP=abc
When I perform the same steps, setting INSTALLDIR=abc on the command line and setting INSTALLDIR=[INSTALLDIR] on the InstallWelcome dialog, I can see the value I passed to INSTALLDIR on the command line. I was under the impression setting command line properties overrode all other properties except those set by the operating environment. At what point in the UI or Execute sequence are properties set on the command line available for use during the install?
That should work, and a simple test at this end seems to turn out okay. If you create an MSI log file when you launch your installer, there should be a line like this:
I tried this on a new basic msi and it failed to display the property value in the text box. I checked the log files for both and they looked ok. Command Line: BIFF=hello SETUPEXEDIR=C:\InstallShield 2012 Spring Projects\My Project Name-2\PROJECT_ASSISTANT\SINGLE_EXE_IMAGE\DiskImages\DISK1 SETUPEXENAME=setup.exe CURRENTDIRECTORY=C:\InstallShield 2012 Spring Projects\My Project Name-2\PROJECT_ASSISTANT\SINGLE_EXE_IMAGE\DiskImages\DISK1 CLIENTUILEVEL=0 CLIENTPROCESSID=4776
So why doesn't something simple like this work for me?
I don't see an obvious reason that would happen in a new project, without something like a typo in the property name (MYPROP=[MUPROP]) or a bad space between the brackets (MYPROP=[MYPROP_]). Could you zip up and attach the new project file?
I have included a zip file of the project. I have created an InstallScript MSI and it too does not display properties after doing a msigetproperty. I have tried to get INSTALLDIR and it always comes up blank.
The value not showing up in InstallScript MSI could be a separate issue. InstallScript dialog boxes don't expand [PROP] expressions, and MsiGetProperty needs a bit of prep (such as setting a buffer size) to return a value.
