I tried installing QC 10 and it din't work properly. It says some components dint install completely. so can anyone suggest me how to solve this problem!!!
What are the issue ? client issue or what kind of error you are getting?
You need to run IE as an administrator so it has privileges to install.
Also can take hint from this thread. It is one of common issue for accessing QC in initial stage.
