Install_Init (Compact 2013)

4/15/2013

A custom installer dll should export the Install_Init function. This function will be called before installation begins. This function can be used for custom operations such as checking an application version for application re-installation or determining whether a dependent application is present.

Syntax

codeINSTALL_INIT Install_Init(
  HWND hwndParent,
  BOOL fFirstCall, 
  BOOL fPreviouslyInstalled,
  LPCTSTR pszInstallDir
);

Parameters

• hwndParent

• fFirstCall

Return Value

• codeINSTALL_INIT_CONTINUE
  Continue installation.

Remarks

This function may be called multiple times, each time with a different string for pszInstallDir. For example, when the current directory does not have enough room, you should call this function for the first time. .

This function is called during installation, before the installation process begins.
