Did the Application Catalog work before Upgrading to ConfigMgr 2012 R2 SP1?

i have installed CU1 for SCCM 2012 R2 SP1

before install CU1, everything worked fine

Are the prerequisites installed? When you reinstall the Application Catalog does the sitecomp.log indicate a successful installation?

Seyed,

I have a feeling I have encountered a similar problem with the App Catalog when moving it back to the site server after offloading the role to a site system. I believe I have CU1 installed. Unfortunately my lab has just died on my so I can't confirm at this stage. 

I tried various things to get the credentials to disappear but couldn't. 

If you try with IP address I believe this gets you logged in but apps do not appear. Can you confirm this?
