directory are copied to a directory with a name that resembles this pattern:
C:\icm\bin\_ICM_7_2_1_0_0_0_44.

A list is kept in a text file for every backup directory created. This file is written to the product
root directory (example: C:\icm\_ICM_7_2_1_0_0_0_44\Return_ICM_7_2_1_0_0_0_44.txt).

How to Manually Return a Failed Release 7.2(1) Installation to the Pre-installation State

Perform the following steps to manually return a failed Release 7.2(1) installation:

Note: This process must be followed only if the Add/Remove Programs uninstallation procedure
fails.

Locate all the backup directories using the return list file.

Copy all of the files in each backup directory to its immediate parent directory.

Delete the backup directories and all their contents.

Note: While the deletion of the backup directories is functionally optional, it helps to keep the
system clean. In the event you do delete the backup files here, it might be worthwhile to store
them in a safe location elsewhere.

Clean up the registry by removing the Installer information.

For example, the Installer information for ICM_7_2_1_0_0_0_44 is removed by deleting this
key and all its contents (HKLM\SOFTWARE\Cisco Systems,
Inc.\Patch\ICM\7.0\Patch\ICM_7_2_1_0_0_0_44).

If a new language selection was made during the install, the language selection must also be
reset by modifying registry named values under the key HKLM\SOFTWARE\Cisco Systems,
Inc.\ICM\SystemSettings.

a.

Copy the value of "Last Language" to "Language".

b.

Copy the value of "Last LanguageAbbrev" to "LanguageAbbrev".

While the previous instructions restores most ICM nodes, more needs to be done for a WebView
deployment. WebView places many additional requirements on the Installer, such as copying
files from a base repository to each WebView instance, updating templates, cleaning out caches,
etc. There is no easy way to manually recover the WebView changes. However, if the manual
recovery previously described is followed, the Installer might be safely applied again, and
recover the WebView deployment. When a successful installation of this minor release is
deployed, the uninstallation program can be run normally to restore the WebView state to
pre-installation configuration.
