condition on features
how can I install a feature based on a system search
I have 2 features but I want to install only one based on a condition in the registry
I have created the system search property based on the 2 reg keys
and I have conditioned the components in each feature
ie hklm\software\servera appsearch STRFINDA
hklm\software\serverb appsearch STRFINDB
feature A
component A
condition STRFINDA=regvaluea
feature B
component B
condition STRFINDB = regvalueb
this works fine but how do i condition the features instead

install level in the property table is set to 100
That sounds a bit high, ofcourse depends on the default installlevels of your 2 features. But try the following:
Set INSTALLEVEL in property table to 3
Set InstallLevel of your 2 features to 4
Set level value in Condition table to 3
Make sure all features that always get installed have installlevel of 3 or lower.
If you want to use higher values, go ahead, but keep the same higher-lower relationships.

Presumably, 'regvaluea' and 'regvalue' are the actual values you're expecting to be returned? That is, if you're testing for, say, an uninstall string, then 'regvaluea' would be the actual string.
Equally, I presume you have STRFINDA/STRFINDB initialised to zero in the Property table?
Why not post (in CODE tags, so that you can space things out nicely) the AppSearch, Condition, Property and RegLocator tables?

Give us a clue bob - what's in your Condition table? What's your install log saying? You might want to look into how the InstallLevel property affects whether features are installed or not, and possibly re-evaluate the value you have entered in your 'Level' column.

feature_ level condition
A 3 STRFINDA=regvaluea
B 3 STRFINDB=regvalueb
A 3 STRFINDA=regvaluea
B 3 STRFINDB=regvalueb

....and I think your InstallLevel property will have to be at least 3 for these conditions to work too....if it's less than 3, the features wont install regardless of your conditions.

At what Level are the features by default? I hope it's above 3...

STRB New signature 2
The space before the 2 is a typo? If it is in your tables remove it.
Also what's the default INSTALLLEVEL of your MSI set to?
If I'm not mistaken it should be lower than the default installlevel of the features (so they don't get installed by default) and the level value in the condition table should set the installlevel of the features to lower than or equal to your MSI's INSTALLLEVEL.
Hope it helps
