Welcome to Android Central! Which phone? Try going to Settings>Apps>All, select Google Play Store, and Clear Cache/Clear Data, then Force Stop. Do the same for Download Manager. Now try again.

If that doesn't help, then go to Settings>Accounts​, and remove your Google account, then add it back again.
