Setting registry keys for a bottle
You may encounter tips, guides, or instructions for troubleshooting issues that ask you to set registry keys for windows applications. Each bottle has a separate registry, and registry keys set in one bottle do not affect other bottles, however note that registry keys set in a given bottle may affect all applications in that bottle - this is another reason to install your applications into their own, separate bottles (unless you have a good reason not to).
There's a great breakdown of useful registry keys
over at WineHQ. In this guide's example, we'll set the "useGLSL" key to "enabled".
To get started, you need to access the registry for a given bottle. Launch Crossover, then highlight the bottle in question and click on "Run Command":
In the "Run Command" window type "regedit" in the "command" field and click "run":
This will open up the registry editor:
Now, browse to the location specified in the instructions you're following. Again, for this example we'll add "useGLSL=enabled" to "HKEY_CURRENT_USER/Software/Wine/Direct3D", which is a fairly common value to add for 3D games.
note - it's fairly common to abbreviate "HKEY_CURRENT_USER" as "HKCU", "HKEY_CLASSES_ROOT" as "HKCR", as so on.
Browsing to "HKEY_CURRENT_USER/Software/Wine", we see that "Direct3D" isn't there, yet:
To add "Direct3D", right-click on "Wine" and select "New>Key" (or highlight "wine" and go to "Edit>New>Key>"):
And then name the "New Key" entry that appears (we'd name it "Direct3D" in this case):
To add "useGLSL=enabled", which is a string value (the instructions you're following should indicate what type of value you need), highlight the new "Direct3D" key, right-click, and choose "New>String Value" (or highlight "Direct3D" and go to "Edit>New>String Value"). This will generate an entry in the right-side panel:
Name it "useGLSL", hit "enter", and then right-click and choose "Modify" (or "Edit>Modify"):
Type "enabled" in the "Value data" field, and click "ok":
That's it! The String Value "useGLSL=enabled" has now been added to "HKEY_CURRENT_USER/Software/Wine/Direct3D".
And there was much rejoicing...
