I have received notifications of versions 1.83 and 1.84.
I've successfully downloaded these but...
OS is Windows 10.
Eiother your temp folder is full and youi haven’t enough disk space or it has had its attributes reset. Alternatively your anti-virus may be blocking it.
Try running install 'as administrator' and also I'd suggest turning your anti-virus off during the installation - there are no virii although some A/V programs think the installation software is a virus - it's not.
SOLVED!!! 1200 thanks (1000 thanks + VAT)
It was indeed my AVG Anti-virus being over-cautious.
There’s actually a pinned post explaining all that LOL
