I cannot load the client. I keep getting the message "Application cannot be started. Contact the application vendor. "

I am running Windows 7 64 bit. I think the problem is the client is running on 32 bit and cannot be read by the 64 bit system. Could that be the problem? is there a 64 bit version of the client? If not, then I will have to cancel my Premium account since I am updating my mods one by one manually.

When I ask for details on the error this is what I get:

Somehow your ClickOnce appstore has gotten corrupted. You can correct this by doing the following:

1. From the Windows Start menu choose Run (Or Windows Key + R)
2. Enter the following, depending on your version of Windows, then click the OK button:

   On Windows VISTA / 7: %userprofile%\AppData\Local\Apps

3. Delete the 2.0 folder
4. Run or Install Curse Client v4
