Straight from the tutorial: "The term NOT (!FeatureName = 3) means the feature
is not installed locally."
So since I want the install to stop if the feature *is* already installed in my
product.wxs I have:
<Condition Message="FeatureA already installed">
<![CDATA[(!FeatureA = 3)]]>
</Condition>
Problem is this *always* stops the installer even when the software is not
installed!?
Scenario:
1. Software not installed.
2. Install via msi installer. No issues.
3. Try running installer again. It stops with "FeatureA already installed"
message. So far so good.
4. Remove software with Control Panel->"Add or Remove Programs".
5. Try running installer again. It stops with "FeatureA already installed"
message. Bzzzt. THIS IS CLEARLY WRONG!!
I have even tried rebooting XP after the removal via CP but that has no impact.
Also looked in the registry after removal via CP, but cannot find any software
remnants.
Any ideas on what's going on and how to make it work?
Thanks.
