Zoho Writer and Zoho Sheet error messages

I'm having an error message when trying to login using the plugin in Office Word 2007 in a Vista machine.

Error:

"An error ocurred while configuring the local setup for the user. Please check the System Space and access permissions for the folder."

Then nothing in the addin works. Same with Excel.

Q: what folder is created by the setup for local use?

I have read similar posts in the forum without any solution.

Note: I'm the administrator of the machine and move the user profile to another disk.
