i am having trouble getting the correct feature state when i call the MsiGetFeatureState function.  I always get a value of 2 which represents INSTALLSTATE_ABSENT.  I assume this is happening because it can not find the feature which i have passed in as a parameter.  But i do not know where i am going wrong because i am hard coding the feature name into the function call.

ie.

lState=MsiGetFeatureState(hMSI,"featureName",installState,tempNum);

i always get a value of 2 for installState.

Any help or suggestions would be appreciated

Try checking the value of your tempNum variable. I think the function is not documented very well.

MsiGetFeatureState returns two integer values.  The first integer gives the current state of the feature.  If you are performing an installation on a machine for the first time, then the value of two is correct, because the feature currently doesn't exist on the machine.

The second integer is the action state of the feature.  This is what is going to happen to the feature during this installation.  For example, if the feature is going to be installed to the local drive, it will have an action state of 3.

Hope this helps.
