Installation and Registry association

[Guest]

Hi,
I have 3 C# programs (version: 4.6.0; 4.6.1; 4.7.0) now.When I firstly
install v4.6.0 and next v4.6.1,that is ok---that means v4.6.1 becomes the
current program to open the project file(extension .ws) when you double-click
the project file. So are v4.6.1 and v4.7.0, v4.7.0 becomes current program.

But the problem is that is not ok for v4.6.0 and v4.7.0, because v4.6.0 is
still current program. Information: REG_SZ "C:\Program
Files\xxx4.6.0\xxx.exe" "%1" in the Registry HKEY_CLASSES_ROOT is still
v4.6.0's path,not the latest v4.7.0 installation's path.
So are v4.6.0, v4.6.1 and v4.7.0, v4.61 becomes current program.I do not
know why? It should be that the last installation program become the current
open program.
Could anyone help this problem?
