'Unable to find a version of the runtime to run this application'
I have .NET 4 installed on my XP machine but I get this error.
I see from another link it needs .NET 3.5. Would I have to downgrade?
Yes, You do need .Net 3.5 http://www.microsoft.com/en-us/download/details.aspx?id=22
Thanks. It works fine on my Vista with 3.5 but I need .NET 4 on the other PC.
Will your app. be compatible any time soon?
.NET 4.0 and .NET 3.5 can both be installed on the same machine.
Ok thanks, will try again
You should really put a little note that mentions requiring .Net 3.5. It can be quite misleading.
ON the website?
Wherever you see fit. Maybe a requirement/prereq page.
