Hi!
In Installscript im using
retFeature = MsiGetFeatureState ( ISMSI_HANDLE, "FeatureName", sFeatureState, sActionState );
to determine in which feature and in which mode I am. But I'm really confused about the values of sFeatureState an sActionState.
During Custom-Installation
- selected feature sFeatureState = 2 and sActionState = 3
- unselected feature sFeatureState = 2 and sActionState = 3

During Modify:
- selected feature sFeatureState = -1 and sActionState = 3
- unselected feature sFeatureState = -1 and sActionState = 2

During Uninstall:
- feature sFeatureState = -1 and sActionState = -1
but on at another feature: sFeatureState = 3 and sActionState = 2 or  sFeatureState = 2 and sActionState = -1

Does anyone know how to handle the return values of MsiGetFeatureState, or has a better idea?
The Installscript-code should only be executed when it is an selected feature and is not in uninstallation-mode.

Thanx

Is this a standard or a Basic MSI project?

Where in the sequence is this code being run?

Hi!
It's a MSI project and some features rum just before InstallFinalize and some must run after.

Some "features" run after InstallFinalize?

You mean some CustomActions, surely?

You should be very careful what you do after InstallFinalize because you lose some of the properties and such.  I've had some bizarre results trying to do things at the end of an installation and managed somehow to squeeze them all into the deferred area instead.  Any hope you can do the same?

[Heike]

I' ve managed to move almost all features before InstallFinalize, but the results of MSiGetFeatureState are still confusing. In a InstallScript Function I must now in which mode I run, especially the UnInstall-Mode. Is there any other possiblity to recognize in which mode the setup run?

Not from within the script.  You can put conditions on a CustomAction based on Feature States and Actions, but I'm not sure it'll be much less confusing.

See the bottom of article "Conditional Statement Syntax" in the MSI Help file for information on that.  It may go some way to explain the feature states you're getting too.
