ILM 2 Beta 3 Premature Failure - ilmpasswordportal.wsp already exists

I seem to discover all of my errors during the installation. :)

If you've had a premature failure sometimes you'll see this error in the log:

CAQuietExec:  Executing solution-deployment-microsoftidentitymanagement.wsp-0.
CAQuietExec:  The solution-deployment-microsoftidentitymanagement.wsp-0 job completed successfully, but could not be properly cleaned up.  This job may execute again on this

or this...

CAQuietExec: 
CAQuietExec:   A solution with the same name "ilmpasswordportal.wsp" or id "df66f0f3-ac0a-4781-b28a-66ec92377aea" already exists in the solution store.
CAQuietExec:  E:\Program Files\Microsoft Identity Management\Web Portals\ILMPasswordPortal.wsp: The Solution installation failed.
CAQuietExec: 
CAQuietExec:  Error 0xffffffff: Command line returned an error.
CAQuietExec:  Error 0xffffffff: CAQuietExec Failed

Here is how you clean it out:

1. Open SharePoint Central Administration
2. Click the Operations Tab
3. Under Global Configuration, click Solution Management

You should see this:

1. Click the hyperlink for offending WSP

You'll probably see something like so:

1. Click the Remove Solution link and click OK to delete the WSP file

Now you can try your reinstall again...
