Description agctools 2005-06-15 12:19:05 UTC 
NetBeans 4.1 installer doesn't detect the installation, so user can install more
than one NetBeans 4.1 on the same machine. That can cause some consistant problem.

please try the following test case:

1, Install NetBeans 4.1;
2, Install NetBeans 4.1 to another new directory;
3, Install Mobility pack. The mobility pack installer can detect the NB41
installation directory during the installation.
4, Uninstall mobility pack and the second NB41 installation.
5, Install Mobility pack again. The mobility pack installer could not detect the
NB41 installation directory automatically. User have to enter the directory
manually.

I suggest the installer should check the registry table to find our if NB4.1 is
already installed, and prevent the installation if it is already installed.

Multiple instances (installations) are allowed on the same machine by design.
(Even the same IDE version.) Unfortunatelly it can cause some confusion when
installing/uninstalling as you describe. You can still use Browse button to
locate valid installation of IDE yourself.
