Our ARIS 9.8.3 stopped working all of a sudden and we are not sure why.  We have ARIS Architect Designer installed on a WIndows 2008 R2 STandard with Service Pack 1.  The ARIS Agent 9.8 service will not start and I also see that IIS or APACHE were not installed on the server.  Is there ACC for 9.8.3?
