[wix-users] Can we reset NeverOverwrite setting in a Patch.msp

[Blair Murri]

That should turn that bit off during your small update, but it will still be off in the next maintenance patch after this one.

If you have been protecting those config files in order to prevent loss of customer settings, you may want to instead consider a custom action to rewrite your changes to that file. WiX provides a couple, one intended especially for config files (because it supports XML namespaces) that may do the trick.

Subject: [wix-users] Can we reset NeverOverwrite setting in a Patch.msp

Hi WiX Users,

Below is my question-

We have certain web and app.config files which are set as
NeverOverwrite='yes' in the Major Release say 17.0 MSI1 (Setup.msi), so
that they wont be overwritten during subsequent maintenance patches.


*<Component Id="ServiceConfig" Guid="xxxx-xxxx-xxxxxx-xxxxxx-xxxxxxx"
NeverOverwrite="yes">            <File
Name="Dom.Common.Attributes.dll.config" Id="fileB12346799C67BADJB3456VT688"
KeyPath="yes" />*

Now we have a change in those config files which need to be delivered in a
Patch.msp.
If we build a maintenance MSI2 (which has our latest changes to the config
files) by setting the above component NeverOverwrite='no',will the diff
Patch.msp generated out of MSI1 and MSI2 install/overwrite the older config
files with the latest ones?

Or should this only be done by a Major Upgrade MSI?

Thanks,
Mounika.
