First of all, do you know that one can install .NET Framework v.4.0 on any system where v.3.5 can be installed; and I don't see any reason for not doing it. (This is v.4.5 which cannot be installed on XP.)

However, you can re-target your projects to any version starting from v.2.0 (the .NET versions prior to this version hardly can be considered seriously). With Visual Studio, this is just a few clicks per project. Change target framework using the option [Project Properties] => The tab "Application" => "Target Framework".

Of course, after you change the target, your project will only compile if you did not use any new features of v.4. However, if you used new features of newer VB.NET version, it's fine, will compile.

That's it.

+5. Complete answer. I know I have target machines in my networks that cannot for legacy dependency reasons not have dotNet 3, 3.5 or 4 installed, so it's very good to mention how to "downgrade" an application as well.

Thank you, Marcus.
Yes, the real blocking reason is having Windows 2000, which I still use, too. It can work only with v.2.0, but I easily create compatible assemblies using VS 2008 or 2010, as in all my articles (yet another reason to downgrade is preparing of CodeProject publications; a nice published code provides solutions for all compatible platforms).
