20. I receive an error when I launch mangos "You have _outdated_ DBC files."
What does this mean?
Your game client version that you extracted the DBC files from does not match the mangos server revision.
How do I fix?
There's plenty of threads that mention this problem. Use the forum search, located beneath the Mangos banner at top of page.
Either download W0W patch, and update client then run the extractor(ad.exe) or update mangos, compile, and run the extractor. Also make sure you're not using an old ad.exe from an earlier mangos compile and be certain it is extracting from a WoW directory that has the version needed. How do you find what client version your mangos server supports? Refer to FAQ 6.
21. I receive an error when I launch mangos "<FILE>.dbc (exist, but have x fields instead x) Wrong client version dbc?"
What does this mean?
This is similar to FAQ 20. Mangos is referencing dbc files that do not match its rev. You need to make sure your WoW client version is supported by your Mangos version before you extract the dbc files. More than likely you updated mangos to support newer patch but you did not re-extract dbc files from newly patched client.
How do I fix?
Look at the datadir line in the mangosd.conf file and make sure it points to a directory that has dbc files that match the mangos rev you are running. Update client or mangos then re-extract (ad.exe) the dbc files from WoW client folder. How do you find what client version your mangos server supports? Refer to FAQ 6.
22. When I try to launch Mangosd.exe I receive an error: "The application configuration is incorrect. Please reinstall."
What does this mean?
You compiled mangos with Visual Studio, or Visual C++ Express, on one computer, and moved the files to a different computer.
How do I fix?
You will need to download and install the Microsoft Visual C++ Redistributable Package onto the computer that you are receiving this message, the computer you are trying to run mangos on.
Download here: Microsoft Visual C++ Redistributable Package
Also, it would not hurt to download the latest .net framework from Microsoft.
