Install GRE on Windows in silent mode

Install Genero Report Engine on Windows® platforms using the MSI installer.

Important: Before you install the GRE, you must install the Java Runtime Engine (JRE).

The msiexec utility provides the means to install, modify, and perform operations on Windows Installer from the command line. The /qn option allows you to install in silent mode. The msiexec utility expects an msi file. To be compliant with Microsoft® User Access Control (UAC) requirements, the msi file is embedded inside an exe file. To extract the msi file from the exe file, use the /x option:

c:\fjs-grj-version-build-osident.exe /x

For example:

c:\fjs-grj-3.20.06-build166789-w32v141.exe /x

A msi file is created in the same directory and with the same name as the exe file.


Table 1 shows the most common options for msiexec relating to installation and un-installation.
