Just lost all files on a 128GB SanDisk SDCZ50-064G-B35 Cruzer Blade - HELP NEEDED

Does veracrypt require admin permission?  On personal computers that may work but on pcs owned by others it probably won’t.

-edit-

Yes, it does.  https://veracrypt.codeplex.com/wikipage?title=Using%20VeraCrypt%20Without%20Administrator%20Privileges

Using VeraCrypt Without Administrator Privileges

In Windows, a user who does not have administrator privileges can use VeraCrypt, but only after a system administrator installs VeraCrypt on the system. The reason for that is that VeraCrypt needs a device driver to provide transparent on-the-fly encryption/decryption, and users without administrator privileges cannot install/start device drivers in Windows.

And whether veracrypt or some other app is better than SecureAccess is not the point.  SecureAccess is the app sold with SanDisk drives and this is the SanDisk forum.  I suggest you get a SanDisk flash drive with SecureAccess and try it.  That experience plus your technical expertice would make you very helpful to users having SecureAccess problems.  imho  I’m surprised your Extreme Pro didn’t have it.
