The Confirm Installation Choices dialog box (shown below) identifies all products automatically selected based on the licenses detected for installation.
If no products are listed and the *** NO PRODUCTS SELECTED *** sentence displays, then the installer did not detect any valid or current licenses. PADS Flow products can still be installed, but may not run until a valid and current license file is installed.
The license file can be installed at a later time via the Start menu > PADS VX.2.6 (32-bit) > PADS Licensing Assistance > Install License File VX.2.6.
In addition to the list of products, the installation location appears (C:\MentorGraphics in this example), along with the Release (PADS VX.2.6), the PADS Projects location (C:\PADS Projects), and the (disk) Space required and Space available.

Install — starts the product installation with the default selection of products.
Modify — allows you to proceed with “Modifying Product Selection and Target Locations”.
The installation begins after clicking the Install button. There are a few stages that the installation goes through, including:
running of self installation scripts
running pre-installation scripts
main installation (where the files are copied to the target)
running post installation scripts
Each of these stages progress from 0 to 100% so it may look as though the installation is going backwards but, in fact, it is probably just progressing to the beginning of the next stage.
Additional dialog boxes may appear during the self and pre installation phases (before the main installation), and during the post installation phase (after the main installation). An example of a dialog box that comes up during the post installation phase is the MGC EBS Registrator.
It is critical that these dialog boxes and any blank DOS (command prompt) dialog boxes be allowed to finish, and to close on their own. Terminating any of these dialog boxes before they complete may result in an incomplete and non-functioning installation.
After a successful installation, proceed with “Completing PADS Installation”.
