I've recently had an issue where MSDTC was unable to start up.

The error in the command line when running `net start msdtc` indicated that there were configuration issues.  
I went into the registry and set the configuration settings to the same values as a default installation of MSDTC.

Afterwards, MSDTC was able to start up, however the local dtc seems to be missing in the component services.

I've since followed the steps here.  

 1. `net stop msdtc`
 2. `msdtc -uninstall`
 3. `msdtc -install`
 4. `net start msdtc`

And the steps here.  
Which is the similar procedure as above only with also deleting the registry configuration.

I've also put back a registry backup and rebooted.  
And rebooted after reinstalling.

So far no matter what, the local dtc is hiding from me.  
Does anyone know what might be wrong here, and how to reinstall the local dtc?
I've made an identical post on serverfault.

Have you performed the installation with an administration command prompt, it will not install with a standard command prompt due to UAC and will not error out.  Also I saw your other post on serverfault, you stated this is 2012 not 2012r2, R2 has the new power shell commands and 2012 does not, they are different operating system versions, not an upgrade.

Try to remove application role and reinstall application role
