The following five steps are used to generate a silent installation of Bentley Building Mechanical Systems / Bentley HVAC . These instructions were developed for an InstallShield 6 installer used by Version 8 of this product.
Note that for every new release for which you wish to use a silent installation, you must develop a new silent install. The response file (.iss) is specific to each release of the product.
It is assumed that you wish to use the silent installs to install the product to machine where it is not already present. Also, it is assumed that there is only one version of the required base product on the machine(s) you are installing to. So for generating a silent install of Bentley Building Mechanical Systems / Bentley HVAC the environment should have:
From the command line, run the setup.exe with the parameter "-r" or "/r", to begin a normal UI install. During the install, make those installation choices that you will want the silent installation to perform. At the conclusion of the installation, the file setup.iss will be generated in the %windir% directory, typically: c:\windows\setup.iss.
You must first uninstall the product which you just installed to generate the .iss file. In the case of most Building products such as TriForma, Bentley Building Mechanical Systems / Bentley HVAC , Bentley Architecture and Bentley Structural, you will also need to remove the following file/folders which are not necessarily removed by an uninstall.
To confirm that you have completely removed all traces of the previous installation, you should run a normal UI installation, and stop after you accept the License Agreement. If the next window after the License Agreement states "... project files present" and offers Remove and Backup options, then there are still parts of your previous installation present. Cancel your install, and remove the parts -- repeating the process until this "project files present" window does not appear.
After confirming that you have completely uninstalled the product, then perform a silent installation using the .iss file you generated. From the command line, run the setup.exe with the two parameters: "-s" and "-f1<path to setup.iss>"
For example, if you left the setup.iss at the location it was generated at, then the command line would be: "setup.exe -s -f1c:\windows\setup.iss" No installation windows will appear during the silent installation, although you may notice signals of the silent installation such as a busy cursor.
To determine whether the silent installation completed successfully or not, open the log file generated in the %windir% directory, typically c:\windows\setup.log. A successful silent installation will generate the following section in the log file:
and of course you should have a correctly-installed product.
The most typical failure is:
In this case, the silent installation probably discovered dialogs which were not listed in the setup.iss file. For example, if you correctly developed an .iss file for an environment without Bentley HVAC being present, but ran that .iss in an environment in which Bentley HVAC was in fact not completely uninstalled, then a "...project files present" dialog would be raised. Because this dialog would not have been registered in the setup.iss file, the install would fail with the above -3 error.
