2020.01 does not warn or uninstall other installations

[ToddAndMargo]

Dear Rakudo Star,

I just installed rakudo-star-2020.01-01-win-x86_64-(JIT).msi on Windows 7 SP1, x64 and Windows 10-1909 x64

Found out the hard way if you do not uninstall the prior version, the current version will not uninstall it for you.

Prior installation was rakudo-star-2019.03-x86_64 (JIT).msi

raku -v

@ToddAndMargo thank you for your feedback. We are working on enhancing the installer and will definitely look into this issue.

Hi Hankache,

This image is how Quickbooks handles the situation: [(https://www.dummies.com/wp-content/uploads/qb2020-installation-location-window.jpg)]

Also do not forget to update the system PATH variable to the default installation, if installing multiple installations.
