I am attempting to write new values to the Registry with a Wix
installer on a Windows 7 box. On the first installation the settings
are written properly, I then uninstall the application and find that
the Registry settings are still there (which is what I want).
When I try to install again, or use an installer that reads/writes to
the same Registry settings the new value I provide is not filled into
the Registry setting. The following is my component that writes to the
Registry.
<Component Directory="IISROOT" Permanent="yes"
Id="DBConnectionSettings" KeyPath="yes" Guid="THEGUID" >
<RegistryKey Root="HKLM" Key="SOFTWARE\MyCompany\DbConnection"
Action="create">
<RegistryValue Type="string" Name="Server" Value="[SERVER]"
Action="write" />
<RegistryValue Type="string" Name="Database"
Value="[DATABASE]" Action="write" />
</RegistryKey>
</Component>
It looks like from the log file that the settings are being read in
from the Registry but not being overwritten by whats provided at the
command line however the UI values do overwrite the Registry settings.
Can anyone provide some direction on how to override these settings
from command line?
