I currently work (as you all probably know by now) on an installer for our
software.
Now I have a new problem which I need a bit of input on.
My installer installs five windows services. This is all good and the services
are installed correctly.
They are not started for various reasons, but this has been tested and that
works as well, should it be necessary.
Uninstallation, however, is giving me a bit of a problem. On Windows XP there
is nothing wrong, and the services are stopped and uninstalled fine.
On Windows 7, however I get a warning that the installer will have to reboot
when done.
If I stop the services manually, there is not problems, then it uninstalls
beautifully.
In other words, it seems that the installer cannot stop the services when
uninstalling on Windows 7. This is true regardless of whether I uninstall from
Programs and Features og directly through call to msiexec.
The exact message I get is:
The setup must update files or services that cannot be
updated while the system is running. If you choose to
continue, a reboot will be required to complete the
setup.
As mentioned, this is not a problem on Windows XP. My code looks like this:
<Component Id="MessageListenerComponent"
Guid="44FCBFDC-7E2E-4EE6-9E17-30BB4C566421" DiskId="1">
<File Id="MsgListener" Source="$(var.BuildPath)MessageListener.exe"
KeyPath="yes" />
<File Source="$(var.BuildPath)MessageListener.pdb"
CompanionFile="MsgListener"/>
<File Source="$(var.BuildPath)MessageListener.exe.config"
CompanionFile="MsgListener" />
<ServiceInstall Id="MsgInstall"
DisplayName="!(loc.MessageListenerDisplayName)"
Name="MessageListener"
Description="!(loc.MessageListenerDescription)"
ErrorControl="normal"
Start="auto"
Type="ownProcess"
Account="NT AUTHORITY\NetworkService"
Vital="yes"
Interactive="no">
<ServiceDependency Id="MSMQ"/>
<ServiceDependency Id="NSEngine"/>
<ServiceDependency Id="SMI"/>
</ServiceInstall>
<ServiceControl Id="MsgLstnrControl" Name="MessageListener"
Stop="uninstall" Remove="uninstall" Wait="yes"/>
<fw:FirewallException Id="MsgLstnrException"
Name="!(loc.MessageListenerFirewallException)"
Program="[#MsgListener]"
IgnoreFailure="yes"
Protocol="tcp"
Scope="localSubnet"/>
</Component>
There are five services, of which this is the third. It requires NSEngine and
SMI which is two others of our services.
For some reason the installer fails to elevate for the stop on uninstall, but
how do I get it to do that?
Thank you,
Thomas Due
