[Bug]: An app installer will run when Bottles directory is default, but will not run if Bottles directory is custom.

[ThomasAn73]

Describe the bug

Creating an application-type bottle, while Bottles advanced settings is using default directory, behaves differently (finds Gecko and begins the installer) than creating an identical bottle while Bottles advanced settings is using a custom directory (Gecko is not found and installer does not begin).

The bottles are identical except the default path

To Reproduce

With this app: https://files.mcneel.com/dujour/exe/20231212/rhino_en-us_7.36.23346.16351.exe (This report only pertains to the installer window showing up at all, not whether the app itself finishes installing)

1. Create a bottle (choosing "application" environment), add the dotnet48 dependency and then run the app installer --> The installer screen shows up. That's all we need to see (don't try to finish installing).
2. On the main bottles screen --> press the hamburger icon --> Preferences --> Advanced --> Bottles directory --> change it to something else (eg ~/AppsWindows/) --> Now do step (1) --> A blank window shows up (installer fails to run).

Notice that in both cases we chose "applications" environment and in both cases Gecko, Mono, and a few other dependencies were auto-installed. So the two scenarios are identical except the default bottles directory.

The terminal issues the following errors:

wineserver: file_set_error() can't map error: Function not implemented 015c:err:appwizcpl:install_file MsiInstallProduct failed: 1627 Could not find Wine Gecko. HTML rendering will be disabled. 0144:err:mshtml:create_document_object Failed to init Gecko, returning CLASS_E_CLASSNOTAVAILABLE

Just out of curiosity what filesystem permissions, if any, have you given Bottles? Are they default? For example have you given bottles explicit permission for the custom bottles path?
