Mandatory Changes

The following items MUST be changed before releasing a fork of Omaha. Preferably, make these changes as soon as you start development:

Example Company name: "Crystalnix"
Example full URL Omaha server web page: "http://crystalnix.appdater.io"

• omaha\main.scons

_is_google_update_build = False
_FULL_COMPANY_NAME = 'Crystalnix Ltd.'
_SHORT_COMPANY_NAME = 'Crystalnix'
_COMPANY_DOMAIN_BASE = 'crystalnix.appdater'
_COMPANY_DOMAIN = _COMPANY_DOMAIN_BASE + '.io'

---

• omaha\base\const_object_names.h

kGlobalPrefix = _T("Global\\Crystalnix")
Set new uppercase GUIDs for:
kSetupMutex
kShutdownEvent
kCoreSingleInstance
kCrashHandlerSingleInstance
kUpdateAppsSingleInstance
kInstallAppSingleInstance
kGoogleUpdate3SingleInstance
kSetupPhase1NonSelfUpdateJobObject
kAppInstallJobObject
kSilentJobObject
kSilentDoNotKillJobObject
kInstallManagerSerializer
kMetricsSerializer
kRegistryAccessMutex
kOptUserIdLock

---

• omaha\base\const_addresses.h

const TCHAR* const kUrlPing = _T("http://") COMPANY_DOMAIN _T("/service/update2");
const TCHAR* const kUrlUpdateCheck = _T("http://") COMPANY_DOMAIN _T("/service/update2");
const TCHAR* const kUrlCrashReport = _T("http://") COMPANY_DOMAIN _T("/cr/report");
const TCHAR* const kUrlMoreInfo = _T("http://") COMPANY_DOMAIN _T("/support/installer/?");
const TCHAR* const kUrlCodeRedCheck = _T("http://") COMPANY_DOMAIN _T("/service/check2");
const TCHAR* const kUrlUsageStatsReport = _T("http://") COMPANY_DOMAIN _T("/tbproxy/usagestats");

---

• omaha\common\const_goopdate.h

For every "omaha..." replace to "Crystalnix..."
kRegValueServiceName
kRegValueMediumServiceName
kRegValueTaskNameC
kRegValueTaskNameUA
kServicePrefix
kMediumServicePrefix

---

• omaha\goopdate\omaha3_idl.idl

Generate new lowercase GUIDs for every interface and coclass.
For every uuid(...) except uuid(___AUTO_GENERATED_GUID___)

---

• omaha\plugins\update\activex\update_control_idl.idl`

Generate new lowercase GUIDs for every interface and coclass.

---

• omaha\goopdate\resources\goopdate_dll\*.rc
• omaha\goopdate\resources\goopdateres\*.rc
• omaha\mi_exe_stub\*.rc

Update each translation to reflect your company and product. Omaha stores all its localized data in a set of resource-only DLLs, one per language. (The MetaInstaller stub, on the other hand, stores a far more minimal set of translations for all languages inside its EXE.)

---

Build the Omaha with these settings. Try it against our server after the build.

Testing Omaha Against Crystalnix Omaha Server

• Test Application (run as admin):
  GoogleUpdate.exe /install "appguid={5A7490AC-F314-4BD3-9591-7B6E9CEA5560}&needsadmin=True"

Look for GoogleUpdate.exe in these locations:

scons-out\opt-win\staging\
scons-out\dbg-win\staging\

The Omaha client should contact with Omaha server for a version query, then download and install the product.
