Cannot open spreadsheet stored in vault

Working with a Sandisk Cruzer Glide 32G.

Installed the SecureAccess software… setup passwords and I can login and out of the vault.

I pasted a spreadsheet into the vault (Excel 2007).  I can see it.  I can double click it and get a quick screen flash that says “please wait while processing”… but nothing happens.  Excel does not start… nothing.

Suggestions welcome.
