Use the Modify Product Selection and/or Paths dialog box (shown below) to add or remove products for installation and change the PADS Software and PADS Projects target locations.

Product Selection — Select this option to display the Product Selection and/or Paths dialog box where you can add or remove the products to be installed. Using the Name column, you can click the various checkboxes to select or unselect products to install.
Target Path — Select this option to display the Target Path dialog box where you can change the PADS Flow installation location. The default and recommended location is C:\MentorGraphics. Use the Browse button to browse for a suitable Target Installation Path to install the PADS Flow software.
Every PADS Flow (dot) release creates a new version sub-directory under the target location. Therefore, there is no need to manually create a version-specific sub-directory as the installation takes care of this for you. Update releases are not full releases. They are incremental releases and update the applicable PADS Flow (dot) release. For example: PADS VX.2.6 Update 1 updates the files in the existing PADS VX.2.6 (full release) installation.
If you are using Windows Server 2016 as an Administrator, make sure that a default web browser is set; otherwise, the product documentation will not open.
PADS Projects Path — Select this option to change the location of the PADS Projects or WDIR (PADS Designer personal settings) directories. The default for both is the C:\PADS Projects directory, unless the WDIR is previously defined, in which case WDIR defaults to the first value in the WDIR environment variable.
Use the use PADS Projects directory for WDIR checkbox to force the WDIR directory to be the same as the PADS Projects directory. Clear the checkbox to set a WDIR directory that is different from the PADS Projects directory.
Use the Browse buttons to locate the preferred directories.
