The MSIFilename parameter triggers the generation of an MSI database and specifies its filename. Other MSI parameters can work only when you uncomment the MSIFilename parameter.

This parameter produces a Windows Installer with the specified filename in the output directory. You can create an MSI file when you want to deliver packages to remote locations through desktop management systems. Unlike executable files that require the manual use of the thinreg.exe utility, MSI files automate the creation of shortcuts and file type associations for each user.

ThinApp comments out the MSIFilename parameter unless you specify MSI generation during the capture process.

Replacing the MSIFilename Parameter

You can generate an MSI file during the build process and replace the filename with your own filename.

[BuildOptions]
