I have recently got the Expression Web V3 and it is telling me that I have to install the .NET Framework 3.5 Service Pack 1. So I go to the microsoft site t download the .NET SP1 and at around halfway installation it says that there was an error detected and then it rollbacks the installation to 0%. I also get message to check Error Log but I dont know where it is? If I click on MS Visual Studio 2008 then it will come up with an error message saying that "file cannot be opened because it is being used by another application". I then tried to reinstall and then repair .Net 3.5 and this time it was successfully installed without any errors but I am still not able to install the Ex Web 3.0. So can anyone tell me how to fix this issue?
