Oracle Express Edition And Windows Encrypted File System (EFS)

I want to use oracle express edition with windows encrypted file system. I tried some possibilities like encrypting xe folder. But connection can not be established when efs is used. Is there a compatibility problem between oracle xe and windows efs? On Oracle's page, it is declared that oracle database is compatible with Windows EFS.
Thank you for help.


Pl identify which version of Win 7 - 32-bit or 64-bit ? Home version or something else ?
The 11g XE install is only available for 32-bit version of Win 7 Professional or higher - If you are installing on 64-bit version or Home version of Windows, then you are on your own. What is the reason for enabling EFS on this database ?
