Hi All,
I thought I was on the right track with this, but after some testing
it's not working as expected.
I've defined this in my installer:
<Property Id='UNINSTALL_EXE64'>
<RegistrySearch Id='LocateUninstallExe64' Type='file' Root='HKLM'
Key='SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\{413B7644-1F93-4890-BD40-AC540C29935B}_is1'
Name='UninstallString' />
</Property>
<Property Id='UNINSTALL_EXE32'>
<RegistrySearch Id='LocateUninstallExe32' Type='file' Root='HKLM'
Key='SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\{413B7644-1F93-4890-BD40-AC540C29935B}_is1'
Name='UninstallString' />
</Property>
<Media Id="1" Cabinet="ss.cab" EmbedCab="yes" />
<!-- Custom Actions -->
<CustomAction Id="ca.RemovePreviousVersion64"
Property="UNINSTALL_EXE64" ExeCommand="/SILENT" Return="check" />
<CustomAction Id="ca.RemovePreviousVersion32" Property="UNINSTALL_EXE32"
ExeCommand="/SILENT" Return="check" />
<!-- Installer Sequencing -->
<InstallExecuteSequence>
<Custom Action="ca.RemovePreviousVersion64"
Before="InstallFiles">VERSIONNT64</Custom>
<Custom Action="ca.RemovePreviousVersion32"
Before="InstallFiles">VERSIONNT</Custom>
</InstallExecuteSequence>
As sean said below he uses QuiteUninstallString but in the registry that
is the "path to the uninstall.exe" with a command of "/SILENT" and
CustomActions need a Property (full path to exe) and an ExeCommand. Can
the exe command be specified with an empty string?
Or am I completely barking up the wrong tree with the whole thing at the
moment?
Thanks,
Jammer
