I may have screwed up the appropriate permissions for the service accounts/application pools necessary to get store apps to work. At this point I think I need to start over, but the rest of our Sharepoint install is working. Can I safely remove the App Management Service Application and Proxy plus the Subscription Settings Service Application and Proxy?

Our Sharepoint 2013 installation is pretty basic - just the Sharepoint application server and a 2012 database server.

Hi,

I would suggest you to create a new service application and corresponding proxy, then associate it with your web application and remove the association from your old service application and proxy.

I hope this will help you out.

Hi,

Any Service Application can be deleted and recreated again. Just make sure that your farm is not depended of the service application while you delete it. One way is to remove the association and see if your Web application work correctly! Make also sure if you need to keep the service application database or not! If you choose to delete the related data, SQL databases will be deleted too.

Note that Subscription Settings Service Application can't be created using the UI. You need Powershell, see below:

New-SPSubscriptionSettingsServiceApplication -ApplicationPool "SharePoint Web Services Default" -Name "Subscription Settings Service Application" -DatabaseName "SubscriptionSettingsDB" | New-SPSubscriptionSettingsServiceApplicationProxy 

Yes, you should be able to remove them and recreate them without a major issue.  You'll need PowerShell to recreate at least the subscription settings service.  Here's an article on the whole process.

Hi

I have used  $account = Get-SPManagedAccount "domain\spadmin"
 $appPoolSubSvc = New-SPServiceApplicationPool -Name SettingsServiceAppPool -Account $account
 $appSubSvc = New-SPSubscriptionSettingsServiceApplication ApplicationPool $appPoolSubSvc Name "Subscription Settings Service Application"  DatabaseName "SP2013-SubscriptionSettingsDB
  $proxySubSvc = New-SPSubscriptionSettingsServiceApplicationProxy ServiceApplication $appSubSvc
