Hello WiX community, After the advice given to me yesterday, I've been focusing on the subject I've had least replies on. Basically, I am trying to only write a registry entry if it does not exist and create some keys to go with it, or if it does exist, I want to modify things, and at uninstall time, restore things to how they were. Since my attempts so far combined with examples will probably be more informative, here they come:
<Property Id="PROGID_XYZ" Value="Test.ProgID"> <RegistrySearch Id='ExtXyzRegistry' Type='raw' Root='HKLM' Key='Software\CLASSES\.xyz' /> </Property> That ought to fill PROGID_XYZ with an already existing ProgID, or if the filetype is unknown, substitute my own default handler. <Component Id="ComponentXYZ" Guid="<snip>"> <snip> <RegistryKey Root="HKLM" Key="Software\Classes\[PROGID_XYZ]" Action="createAndRemoveOnUninstall"> <RegistryValue Type="string" Name="SomeWeirdValue" Value="Stuff" /> </RegistryKey> </Component> This created the value in the proper place, but upon uninstallation, it removed the entire key, which makes sense since I asked it to. But in this case, the RegistrySearch was successful, and thus the appropriate ProgID already existed, and I essentially wiped out the file associations. Oops. How can I avoid this? If I were to make it action="create", I would never remove the handler afterwards if I understand correctly. To have it all in a little neat list, these are the requirements I am trying to achieve: * .XYZ exists - make changes in existing ProgID. * .XYZ does not exist - make the .XYZ key, and make my default ProgID. * Uninstallation: .XYZ already existed at installation - place back any settings I overwrote in the 'foreign' ProgID, and remove any new entries I made. * Uninstallation: .XYZ never existed at installation - remove .XYZ and my default ProgID. I have studied conditions, features, components and the various options available to me with a RegistrySearch, but I am pretty much lost. As such I appreciate any advice or examples you folks can give me to work off. :) Regards, Jan Wester ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
