I just finished coding a C# project targeting .Net v4. I’m trying to put this program onto a server running windows server 2003 and I’m running into problems.
I copied the contents of the Release directory of my project onto the server, run the .exe, and an error pops up telling me that in order to run the application I must install v4 of the .Net framework, and asks me if I would like to begin installing now.
I’m fairly certain that .Net v4 is on this machine, though. Looking in the registry I see
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\NET FRAMEWORK SETUP\NDP\
and under that, there is
v1.1. …,
v2.0. …,
v3.0,
v4\Client\1033
Under Add and Remove Programs, there is an entry for the Microsoft .Net Framework 4 Client Profile. Does anybody know of any reason why this machine says I need to install .net 4 when it seems as though it is already installed?
The .Net framework Client Profile is a “cut down” version of the .Net 4 framework with a reduced installer size.
If your application targets the full .Net framework 4 then you need to install this on your target machine in order for it to run. You can see what your application targets in the property pages in Visual Studio:
