configuring installations with registry information

[tuffythecat]

Is it possible to enable/disable features based upon registry key values in InstallShield?
I want to merge a registry file with the registry when the installation begins and then, based upon the contents of the newly merged keys, enable/disable features.
Is this possible?
Thanks in advance for any help! :)

Maybe I don't really get it; you want to first merge a registry-file, and than read from the registry?

However, you can use the systemsearch to search the registry and set properties. You can than use these properties to add/remove certain features.

Yes, the first thing that I want to do is merge a registry file.
And then, based upon values in those merged values, I want to enable/disable features.
I think that I get what you are saying though. I can merge a REG file into the registry, then search the registry for certain keys, extract values, set properties based upon those values, and then disable/enable features based upon those properties.
Thanks! :)

it depends on the sequence order.
from what i understood while reading my log files the regular sequence order seems to be:


OnBegin
AppSearch
LaunchConditions


as you may use results of "SystemSearch" ("AppSearch") as a launch condition, it's executed prior to "LaunchConditions".

so for your objective you'd have to reg-merge during OnBegin, for example.

alternatively, you may insert your own actions into the sequence - before the AppSearch action.

cheers, graven (IS dev 7.04)

PS: also, the described layout means you can't use AppSearch results (i.e. the properties it sets) during OnBegin. they'll be empty, initially. but as already said: you may reorder sequences or insert additional actions into sequence. just keep in mind the sequence order matters ....

As Graven has stated, it will depend on your sequence order, but if that is worked out, you can then just write an action to set a property according to your registry entry value.
You can then set the install level of the feature, using the condition table, in accordance to this property.
