Troubleshooting the Uninstallation Process

Uninstallation is usually straightforward when the previous installation instructions have been followed correctly. This section describes Windows anomalies that can affect the uninstallation of Siebel eBusiness Applications.

Defect in InstallShield Versions Greater than 6.0.x

Customers who are installing or uninstalling Siebel eBusiness Applications, version 6.x on the Windows platform may experience a failure to uninstall that version due to a bug in InstallShield versions greater than 6.0.x.

You most likely have this problem if, on trying to uninstall Siebel eBusiness Applications, you receive a message with the text:

Setup failed to run installation

To determine which version of InstallShield resides on a given machine

  1. Navigate to
  2. C:\Program Files\Common Files\InstallShield\engine\6\Intel 32

  3. Select ikernel.exe and right-click to display Properties.
  4. Select the Version tab to locate the version of the InstallShield engine residing on the machine.

You can prevent this behavior from occurring when uninstalling Siebel eBusiness Applications, versions 6.x.x by using the following workaround.

The recommended procedure is to download a utility created for this purpose from the InstallShield Web site. (Alternatively, you can also install a product that uses the desired version of InstallShield.)

The utility guarantees that the target machine for uninstallation has a proper and known state. It renames the current InstallShield engine and removes associated registry entries from the target machine, so that when Siebel eBusiness Applications uninstallation starts, the program validates that the correct InstallShield engine version (6.0.x) exists in that location.

Siebel Systems takes no responsibility for the state in which a client machine is left after running this utility. This utility is provided by InstallShield to address a known behavior caused by that vendor's product defect.

Therefore, use this utility with discretion and make sure that you thoroughly test it before you distribute it to your users.

You may use this utility on any of the following occasions:
