Can't install QVS 10 - .NET framework 3.5 SP1 or greater needs to be installed

I have Microsoft .NET Framework 4 Client Profile and Microsoft .NET Framework 4 Extended installed. Why can't I install QVS 10?

That happened to me too, just install .NET Framework 3.5 SP1 regardless what the message says.

strange thing is that i have installed server with framework 4.0 and this message didnt appear

The 3.5 version of the .Net framework is NOT included in the v4, they are independent and thus incompatible (it is the same between 1.0 and 2.0, but it's not the case between 2 and 3.5). QVS needs the 3.5 framework, so having the 4th one does not fulfill the requirement.

i understand now why i dont see 3.5 sp1 in installed software list.

i'm using windows 2008. that ships with 3.5 sp1 included, but you need to enable it. When enabled it will install, but not show in the list of installed software.

That's right,

Elaborating a bit for those who need it, that means going to the Control Panel, Programs and Features, and on the left list, Enable Windows Features, Roles, and there you will have .NET 3.

But it does list on my installed programs (Windows Server 2008 SP2).

Regards.

This bit me too!

It actually installs QV10 SR2 with only .NET4 installed, but then all of the services terminate immediately.  The event log says it can't find libraries for .NET 3.5.0.0

You must also install NET 3.5.1, per the instructions posted previously.
