Thanks for the tip, Sebastian! Is there any other way to express dependency
between installations? Is it possible to force uninstallation of dependent
installation?

I'm not uninstalling the service myself. I have tried the component
condition, but it didn't work out. As I understand the mechanics of
installer, when my product is installed the condition is true, so the
component is installed. During uninstalling no matter the condition is false
the installer has to remove already installed component and the service
control is executed. Do I understand it right?
P.S. I've got interesting effect while playing with feature conditions. I
have created sub-feature with the component.
<Feature Id="Sub" AllowAdvertise="no" Level="0" >
<Condition Level="100">ServiceXYInstalled</Condition>
The installer behaves differently when there is no such service on
uninstall:
1) If I run my .msi and choose uninstall, it says it succeed, but the
product still remains installed.
2) If I press Remove from Add/Remove Programs the product is removed from
the system.
In both cases it doesn't try to execute the service control.
