Adrelink: Error: Product Library For Product "IZU" Not Found

When attempting to relink Applications programs using adadmin utility,the following error occurs.

=================================
adrelink: error: Product library for product "izu" not found."izu" might not be listed correctly in your SID_hostname.env file,you may be missing some files for product "izu",or "izu" could be an invalid product.adrelink will not try to link product "izu".Continuing work on other products...
adrelink is exiting with status 1
=================================

Adadmin during the relinking process of product IZU uses the 2 files: izufile.drv and izuRDA.drv. Theissue is caused by those 2 driver files for IZU products which use improper directory names; forsome files there is used "bin" directory instead of "scripts".adadmin is unable to find the following files in their directories when relinking:

$IZU_TOP/bin/rda.cmd
$IZU_TOP/bin/rda.pl
$IZU_TOP/bin/rda.sh

To implement the solution, please execute the following steps:

Note: The issue is resolved by upgrading to file izufile.drv and version 120.4.12000000.7 or higher and file izuRDA.drv and version 120.6.12000000.7 or higher.
1. Ensure that you have taken a backup of your environment,

4. Confirm the following file versions:file izufile.drv and version 120.4.12000000.7 file izuRDA.drv and version 120.6.12000000.7

2. Please backup file $IZU_TOP/admin/driver/izuRDA.drv and apply the following changes:
a)From:izu bin rda.plTo:izu script rda.pl
b)From:izu bin rda.cmd
