After installing Wilco's 737PIC, I lost my "add-on" tab under the menu choses in FSX
That was what corrupted your DLL.XML file, it's a known problem:http://support.precisionmanuals.com/KB/a92/dllxml-information-and-troubleshooting.aspx
Several addons (most notably several by Wilco/FeelThere) corrupt the FSX dll.xml file, which can render inoperative any addon that relies on dlls loaded from it
The installer for GSX found the corrupted dll and created a new one, however, now only the add-on manager works.
It hasn't done just that, it *also* created a backup of the (corrupted) file, before the installation, in the same folder.
If the installer for GSX found a corrupted file/line, why can't I find that line and fix it.
The GSX installer told you exactly which line was corrupted too. If you want to have your addons back, just take the backup file, fix the error caused by Wilco, and save it back as DLL.XML
Our installer will never, ever try to "fix" a corrupted file, since there are many ways it might end up corrupted, so it would be too easy to just make things worse so, it does the only sane choice, which is exactly what it does:
- *alerting* you of the problem
- creating a *backup*
- rebuilding a new correct one from scratch.
