- Is there a possibility to find out, which addons access this file?
Only after you installed them, you can check if they have added anything to dll.xml and/or exe.xml
The one, that corrupted the dll.xml file, was installed after Zurich and before Geneva, because I had no issues to install your LSZH scenery, right?
I don't know what you have installed. However, our installers have exactly the same code that deals with xml files so, if you didn't had any problems with Zurich, it would be exactly the same with Geneva so, you can safely exclude it was something created by any of our installers.
Do you know about addons corrupting dll.xml? If I made a list of my installed addons, would you probably see, which one it is?
We know for sure that Wilco installers modify the file from Windows to Unix, and this confuses other installers like PMDG. However, our installer is able to deal with this, and it will also fix the XML files back to Windows format (which is what FSX defaults to).
Also, there were issues with REX: a certain release was bugged and removed our section (and probably others as well), but I've heard it has been fixed after a certain release.
We don't specifically know of others, but I'm sure there are other addons that corrupts the XML, but we can't say which ones, we can simply DETECT the corruption, by first checking the XML files BEFORE doing anything.
So, the only way to discover which of your addons created the problem, is to run every installer, one by one, and then try to open the XML file with Internet Explorer. If the file has been corrupted, IE will give an error: the same error that would appear if you ran any of our installers, because we use the same syntax checking engine that IE uses.
