How to properly install a new version of ConnectR

It looks like a previous version of ConnectR was installed before on the system:

ConnectR 4.1.7.57

The update to the new version is stuck somehow and preventing the ConnectR 5.0.1.9 from installing;

To resolve this situation requires a 2 step solution:

Step 1. using the Win control panel "add/remove programs" ->remove ConnectR 4.1.7.57

Step 2. make a backup of Win registry of the system and then using Regedit (or other registry editor) remove all registry entries that contain the string 'connectR'.

After the completion of the 2 steps above, you should be able to install ConnectR 5.0.1.9.
