Admin SVC Error when trying to install SharePoint solutions (WSP) and how to fix it

Short and sweet post about deploying SharePoint solutions.  You usually do this by invoking Install-SpSolution under the SharePoint PowerShell, but sometimes you’ll get the following error:

Install-SPSolution: Admin SVC must be running in order to 
create deployment timer job

All you need to do is to go to the Services section in Control Panel\System and Security\Administrative Tools and look for the service called SharePoint 2010 Administration and start it. You might also find that the service is on manual start-up, you can optionally change it to automatic to make sure that the service is always available and ready. Simple isn’t it!
