Hi Michael and Friends ,
a question ....
I have already installed the V4 Beta of October 2018, to install the new Beta of February, I must first delete the one already installed,
or automatically this will replace the other ...
with repercussions also on everything installed, Nodeeditor
Custom Interface and Various Script ... etc. etc.
I know you've already given us answers, but I do not remember
where to look for them ..
If you could help me you would be grateful
alberto
