&FeatureName in condition always return -1

[K0NFUZIUS]

Hallo Installshield experts,
I have a problem with Installshield 2009 Premier.
I try to install a component depending on if an other feature should be installed.
As an example component C1 should only be installed if F2 will be installed.
F1
L C1
L C2
F2
L C3

I found on page 220 in the training manual that this is possible with:
"Conditional Statement syntax"
So I tried to set the Condition of C1 to
&F2=3
I have also tried (&F2=3) AND NOT(!F2=3)

but &F2 seems to return always -1

I was happy to find this solution but it don't work 😞 Has anyone a hint for me.

Thanks a lot

You can associate a component with two features. The component will then be installed if any one of the feature is installed, which seems to be the behavior you seek.

Hi Jeff,
thanks for the answer. No that not what I like to do.
In your case the component would be installed, when selecting F1 or F2 or F1 and F2.

But I don't like to install C1 if F2 isn't selected for installation.

Install C1 -> F1 AND F2
Don't Install C1 -> NOT F1 AND NOT F2
Don't Install C1 -> F1 AND NOT F2

Thanks a lot for further help

I have attached an example:
Please Help!!! 😞
C1 should only be installed if F2 will be installed too
See condition in C1 (&F2=3)

But the condition alwas returns -1. No matter if the Feature will be installed or not.

Please help me
Thanks a lot
