ASP.NET checkout fail while Symantec System Recovery management sollutions installing

Hello!

 

I have a problem when I'm trying to install SSRM solutions. At step, when SIM checking a system for minimal requirements, I get an error of ASP.NET configuration. This the second time, when I'm trying to install it. At first time, I didn't get any errors or warnings. I had to remove that first version and when try to install it again, I get fail. I have found an article with a same problem (http://www.symantec.com/connect/forums/aspnet-error-while-installing-it-management-sollutions-through-altiris-sim), but on my server there is no other Symantec solutions.

 

Could somebody tell me, how to solve this problem?
