Execute Engine

Most high end installation programs use scripting language as a software installation tool to perform special operations during the Setup and UnInstall process. Scripting is a powerful concept, but it requires you to be a programmer and spend considerable time mastering the scripting language and debugging your code.

QSetup features an innovative concept the "Execution Engine". This engine will let you define special operations to be performed during the various stages of the Setup and Uninstall process - using simple selections from dropdown menus rather then script programming in other installer programs.

The "Execution Engine" lets you perform a wide range of operations in a simple and intuitive way. Other software installation tools like "Installshield", "Advanced Installer" or "Inno Setup" implement such operations using very complex and time consuming scripting language. With QSetup, installation of software is more intuitive and easy.

The Execute Engine operations can be:
  • UnConditional
  • Conditional
  • In a While loop.
With QSetup software installer you can specify up to 3 conditions for every operation using the following boolean operators between the conditions: AND, OR, XOR, NOT.

Operations can be performed at the following stages:
  • Undefined Stage
  • Setup Start
  • Copy Start
  • Copy End
  • Setup End
  • UnInstall Start
  • UnInstall End

  • Before User Information
  • After User Information
  • Before Setup Type
  • After Setup Type
  • Before Custom

  • Before Destination

Starting from Version 6.0 the Execute Engine is capable of handling variables.
Using the Execute Engine you can Set, Compare & Use internal variables.

The following commands are Variable related:

  • Set Variable Value
  • Select one of many
  • Input text string
  • Set Case Sensitive
  • Set Whole Word
  • Read Registry Value - (Into a variable)
  • Read INI Item - (Into a variable)
  • Read Environment Variable - (Into a variable)
  • Compare 1 Variable
  • Compare 2 Variables
  • Text Found in Variable
  • Variable Found in Text
  • Variable Found in Variable
  • Variable is Empty
  • Perform Variable Math
A variable is a string item in the form VariableName=VariableValue.
Where ever it is legal to enter a directory alias you may also enter a VariableName in the form: <VariableName>.
Variables are kept across the entire Setup session, thus you can define a variable at "Setup Start" and use it a "Setup End". Variables are also saved from setup to uninstall, thus you can define a variable during the setup process and use it during the UnInstall process.

Detailed description of the entire variables concept may be found in the Composer's help files.
