Hi San2014,
Dear member of SanDisk Community, welcome.
Well, it seems that the file is corrupted.
You have RunSanDiskSecureAccess_Win.exe, which is the version v1.
Download (free) and replace the failed file.
Here it is: http://mp3support.sandisk.com/downloads/RunSanDiskSecureAccess-Win.exe
When you can, in another pendrive, you can now download (free) the new version, V2.
Enjoy, and then you tell us, what happened, please.
Regards, Alfred. (Google translated)
