l.medoshvili Posted December 21, 2015 Report post Posted December 21, 2015 I solved this issue myself. After installing WCF Service and ASP.NET 4.5 I tried to re-install the Application Catalog web service point and Application Catalog website point roles from SCCM 2012 and it worked. Now it's working. But now I have another issue. When I'm trying to request application installation it gives me this error. I'm using HTTP connection. Any suggestions?
