ClinicCore 4.2.16 (54) for Windows x64

Extract this entire ZIP to a folder, then open CliniCore.exe. Keep the DLLs and data folder beside it.
Pre-release testing: use a disposable clinic and fictional records. ClinicCore licensing and enrollment still apply.
Includes the 14 September Google Drive account-switch fix.
Preserve existing clinic installations and backups. Full clinical release acceptance remains open.
The executable is not claimed to be Authenticode-signed. The exact signature status is recorded in the accompanying verification.
Persistent Windows Drive OAuth credentials were unavailable for this build; the existing short-lived sign-in flow can require reconnection.
