Need to access two versions of valut 5.1.1 and 4.1.4

[cynsystems]

I need to figure out how to access two versions of vault 5.1.1 and 4.1.4
I'm currently using VS 2010 with vault 5.1.1
I need to access some legacy code which is stored in Vault 4.1.1
If I try to use Vault Professional Client to access the Vault 4.1.1 code
"The server uses a protocol that is not supported by this client." is displayed

I don't need to integrate with an IED - just need to checkout/view-edit code/checkin
Can I have two versions of client installed on a Windows 7 machine at one time???
Thanks!

If the current version of Vault that you are using is the Professional version, then you can just install a Vault Standard 4.1.4 client and it will work separately from the Professional client. You can download Vault 4.1.4 from this page: http://www.sourcegear.com/vault/downloads2.html. You can also get the client that works with that server by going to http://<your Vault 4.1.4 server>/vaultservice and clicking on the client link.
