The easiest approach is to follow our related Convert EXE(s) to MSI tutorial.
The following article uses options that are available starting with the Professional edition and project type.
In order to exemplify the procedure, we will assume to wrap three EXE installers "one.exe", "two.exe" and "three.exe" into a MSI. Here are the steps:
1. In Product Details Tab (Product Details Page) under "Add or Remove Programs (Control Panel)" group, uncheck the "Register product with Windows Installer" option. We don't want the wrapper to appear in "Control Panel" -> "Add or Remove Programs" as an installed program.
2. Go to Files and Folders Page and add the EXE installers in the "Application Folder".
3. Create a BAT file (e.g. Your_File.bat) with the following content and add it in the Files and Folders Page:
%1 %2 %3
- In the "Properties" group on the right pane set the "File to Launch" field to: "[#Your_File.bat]"
- In the "Command Line" field set this: "[#one.exe]" "[#two.exe]" "[#three.exe]"
- Disable all options from the "Execution Options" group.
- Enable only the "Install" option from the "Execute Sequence Condition" group.
You can create a similar custom action for uninstall as well.
Optionally, because this is a wrapper installer, in the Install Parameters, the interface can be switched to a limited view. Also, to get a starting point on hiding the BAT command window, you can follow our related How to hide the command window of a custom action? article.
