Hi,
I found your post VERY useful as it solved my problem for the weather gadget (see more about the currency exchange gadget later).
However, I'd like to make a few comment and propose a more safe fix than what you propose.
This applies to a situation where the whether target worked on one machine with Windows 7 installed last year (mid 2014) but did not work on another machine on which I had to reinstall Windows 7 this month (Feb 2015) . I mention the dates because it may
have to do with the time at which installation and updating were were made.
- !! OK to replace config.xml of the target machine IF EMPTY (the config.xml of the working machine contains only the instructions for the weather target refresh rate and languages).
--> This file was empty on the machine that did not work.
- !! the folder 168522d5-1082-4df2-b2f6-9185c31f9472 may actually not even exist in the target machine that did not work.
This is probably the main point for correction.
--> This folder did not exist on the machine that did not worK
- !! DO NOT overwrite settings.ini because (i) it is used by the other gadgets ; (ii) you may destroy the settings of these other gadgets.
--> This file was existing on the machine that did not work and contained a lot of configurations I had made for the other gadgets.
All you actually need is to recreate the weather gadge ad then configure it. Then the settings.ini file will be updated and you will have both a working weather gadget AND your other gadgets working properly.
I guess that when people claim that the weather target was discontinued by Microsoft, what really happened is that at some point in time, installation of Windows made it so that the necessary files (config.xml and the 168522d5-1082-4df2-b2f6-9185c31f9472
folder and its content) were no longer automatically created when creating an instance of the weather target.
About the currency exchange gadget, this did not work after the fix. Since it stopped working on several machines at the same time, I guess that the service has been really discontinued.
