Note: LR 11.52 patch will not replace edited configuration files.
I just want to give you a heads up.
In 11.52 patch we changed some of the content of the various configuration files (e.g.. vugen.exe.config in the bin directory or *.addin files in the addins directory). If these files were edited by the user, the patch will not replace them with the new version during installation. This is how Microsoft installer works. In this case you have two options:
1) If you didn't install the patch yet, rename the edited configuration files and install the patch. After installation manually apply your edits to the new file.
2) If you already installed the patch, rename the edited configuration files and run the patch installation again but this time select "repair". After installation manually apply your edits to the new file.
Note that most users shouldn't need to edit the aforementioned configuration files!
For example, if you don't update the vugen.exe.config file you may see an error such as this:
