Application Installers

Omaha client can update any applications and even text files; it just requires a right installer.

Requirements for the application installer to be used with Omaha client:

1. Set one of the following registry keys:

• If you install an application for a machine:
  path: HKLM\Software\{OmahaCompanyName}\Update\Clients\{GUID}
  key: pv
  value: <Version (ex 0.0.0.0)>

• If you install an application for a particular user:
  path: HKCU\Software\{OmahaCompanyName}\Update\Clients\{GUID}
  key: pv
  value: <Version (ex 0.0.0.0)>

Go to Application registration for more information.

2. It must support the silent mode.

3. It should stop the application before a direct update because in common case it's impossible to replace locked resources like libraries and opened files.
