4. On the security tab, under "Group or User Names", click the user that is currently logged on, and then verify that Read and Full Control are both set to allow.
5. Click the Advanced button, verify that the user that is currently logged on is selected, that Full Control is listed in the Permission column, and that "This Key and Subkeys" is listed in the "Apply to" column.
6. Select the check box "Replace permission entries on all child objects with entries shown here that apply to child objects".
7. Click Apply, and then click Yes when you receive the prompt to continue.
8. Click OK twice.

NOTE: For every identity that you have, there may be a subkey under the Protected Storage System Provider key. To resolve this behavior in all of your identities, you must delete all of the user subkeys folders under the Protected Storage System Provider key.
