AppFabric 1.1 un-installation crises , Broken App Catalog Creation - SharePoint 2013

Recently whilst setting up Workflow Manager for SharePoint 2013, I accidentally removed AppFabric 1.1 from application server. This application server was also hosting CA and few Service Applications. Nothing got affected immediately but as soon as I tried to configure Apps Catalog Site Collection I was presented with popular message i.e. "Sorry, something went wrong..."

After checking ULS, I found these two culprits and after jogging my memories I realized that this may be happening due to AppFabric un-installation.

After installing AppFabric 1.1 from below link resolved my issue.

Moreover, during AppFabric installation if you run into issues then this could be due to missing environment variable i.e - PSModulePath. As behind the scene, msi tries to fire some powershell scripts which fail to run in result of this missing variable. 

You will need to dig into msi log files in order to find what exactly causing this. All the best!

After installing AppFabric if it still doesn't work then drag and drop dlls from this location to GAC

C:\Program Files\AppFabric 1.1 for Windows Server

Crises over!
