Tralfazz, help! Homebrew installation gone wrong!

[Tralfazz]

As an additional twist, when I try to launch the game via the old lotroclient, it doesn't accept my password.
I won't touch anything else for the moment...

To run LOTRO using the old version of WINE, you need to edit your UserPreferences.ini file so that the line GameClientType=3 is GameClientType=1 because the old version of WINE does not include the components necessary to run the 64-bit LOTRO client.

I don't know why you are not able to invoke the winecfg tool. Here is a more complicated alternate method for you to try:
1- Launch the Terminal.
2- Go to your /Applications folder in the Finder. Look for the Wine Stable application.
3- Right-click on the Wine Stable application and choose SHOW PACKAGE CONTENTS.
4- Click on CONTENTS.
5- Click on RESOURCES.
6- Click on WINE.
7- Click on BIN.
8- Look for "winecfg".
9- In the Terminal, type "wine" followed by a single space, then drag "winecfg" into the Terminal window. Doing this will populate that command line of the Terminal with the correct path to "winecfg".
10- Hit the RETURN key to run the command. The Terminal will generate some text output and then the "Wine configuration" GUI window will appear.
11- Click on the LIBRARIES tab.
12- Choose a "New override for library:" by using the scrolling list to find "vulkan-1".
13- Click the ADD button to the right of the "New override for library:" selector.
14- Under "Existing overrides:" click on "vulkan-1" – click only once.
15- Click the EDIT button to the right of the "Existing overrides:" selector.
16- Click the radio button to the left of "Builtin then Native".
17- Click the OK button at the bottom of the EDIT OVERRIDE window.
18- Click the APPLY button at the bottom right of the WINE CONFIGURATION window.
19- Click the OK button at the bottom left of the WINE CONFIGURATION window.
20- Close the WINE CONFIGURATION window.
21- Quit out of the Terminal.



You can use the same method to set overrides for the other three libraries and to set the Windows version of WINE to Windows 10, as I referenced in Message #12.
