VaultClient_8_0_1_229 msi failed on Bootcamp 5.1

[chauiprise]

I am trying to install the Vault Standard Version 8.0.1 Client (download vaultclient_8_0_1_229.msi) on my MacBook Pro running Bootcamp 5.1 (for Windows 8.1).
I got the error:
"This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows installer package."
Would you have another installation pkg that I can run with Bootcamp 5.1?

Thanks!

Would it work for you to install the Vault Cross Platform Client that runs directly on the Mac OS?

We haven't made anything specific to Bootcamp.

Which version of the Windows OS are you using on Bootcamp?
