[wix-users] help with wix uninstall setting property to a registry entry for a customaction

[Phill Hogland]

I understand that Merge Modules can be difficult and are only really needed when you plan to distribute the merge module to some other group who is not using the same version of WiX Toolset that you are using.  But if you are using these merge modules yourself, then it would probably be a better plan to create WiX library projects and reference them in the msi project.  The WiX source for the WiX \Setup also uses a WiX library project to author fragments that are used in multiple MSI projects.  I tend to put MSI related code in one Library, bundle related code in another library, and then also create other libraries for certain specific scenarios.

Hi,
Actually I managed to fix it from a post done by rob Mensching The WiX
toolset's "Remember Property" pattern.
<http://robmensching.com/blog/posts/2010/5/2/the-wix-toolsets-remember-property-pattern/>
It does work!! My problem now is that the project i have is using 2 merge
modules I created , 1: one for mysql odbc 2:one for sqlite odbc. the mysql
version even though almost identical uninstalls correctly but the sqlite
version leaves files and the folder on disk. I am stumped with this one.
