1. Log on to Windows.
2. Restore the corresponding Primary User Card or Regular User Card when prompted.
3. The Emergency Card can also be used to decrypt files/folders. 
4. Only the Emergency Card for the Primary User can be used to uninstall OtaniumSuite. 
5. The Emergency Card cannot be used for other purposes such as unlocking the system, opening the OtaniumSuite Control Center, or opening OtaniumKey UI.

The problem is due to Win XP not saving certain file types (eg, .cab, .hdr) necessary for InstallShield to perform the uninstall.  Note that OtaniumSuite can still be uninstalled using the software CD (which contains all the required installation/un-installation information).  Please refer to the following information from Microsoft for further clarification:

This is the definition of which files can be encrypted using OtaniumSuite: 

1. The following file types are NOT encrypted: .exe, .bat, .com, .dll, .ini, .sys. 
2. Shortcuts are NOT encrypted.
3. All files in the Program Files folder (and sub-folders) are NOT encrypted.
4. All files in the Windows folder (and sub-folders) are NOT encrypted.  'Windows' folder refers to the installation folder for Win XP (or Win 2000, etc.).
5. In the Documents and Settings folder, files under the Desktop folder and Start Menu folder of the current user are NOT encrypted.  Note, however, that it is possible to encrypt all files (including shortcuts) in the Desktop and Start Menu folders of other users, including the All Users folders.
6. All files on the Desktop (and in the Desktop folder in Explorer) are NOT encrypted.
7. Files opened (and locked for writing) by another application, eg, Word, are NOT encrypted.  Note that certain applications, such as Notepad, do not lock the file when it is opened; such files can be encrypted.
8. All other files can be encrypted.  If a file is Read-Only or Hidden, the user will be prompted to confirm before encrypting the file.

OtaniumCertificate can save your Private Key in the card.  You can use the key to:

1. Log on to Windows
2. Send secure email. 
3. Digitally sign emails.
4. Digitally sign documents (Office XP)
5. Authenticate yourself to Internet web-sites.

The Certificate Manager under OtaniumSuite Control Center>SmartCard Options provides some certificate management features such as View, Export to Windows, Delete, and Clear All.

For best results, we recommend a maximum of 4 certificates to be stored on the card.  Go to the OtaniumSuite Control Center>SmartCard Options>Certificate Manager and verify that you are not exceeding this recommended maximum.  You can delete one or clear all before applying for a new certificate.

Caution:  Your SmartCard (Primary User Card and Regular User Card) can store up to 4 digital certificates with 1024-bit private keys.  Do not attempt to exceed these limits, or you may accidentally delete required certificates from the SmartCard.

Your network must be PKI-enabled to support SmartCard Certificate Logon.  Check for the following:

1. Do you have an account on this domain?
2. Does this domain server have a certificate service installed, such as Microsoft Certificate Services?
3. Have you requested and installed a SmartCard Logon Certificate onto the SmartCard?

After you have answered yes to all of the questions above, remove the SmartCard from the reader, log off from Windows, and at the Welcome to Windows dialogbox select the option for Use SmartCard Certificate Logon.  Then insert your SmartCard.  You should be able to log on to the PKI server using the SmartCard Logon Certificate stored on the SmartCard.
