IS it possible to do this? I created an unmanaged package in a sandbox, uploaded it, and recaived the URL to install elsewhere. The link to my unmanaged package starts with "https://test.salesforce.com/?ec=302&startURL=%2Fpackaging%2FinstallPackage..." and asks me to login.
But t won't accept me logging into my dev org (which does not have the "test" prefix...). It doesn't take me to an install page, it just logs into my dev org.
