Source file not found install issues

Hey guys,

Trying to install Pro 9 on my PC, I ran the updater before attempting to install and on each VST(Groove Agent SE etc) I’m getting the following error.

I have tried re-downloading the 9-10GB file, but same issue. Any ideas? Thanks in advance!!

Please unzip the folder before trying to install Cubase.

It unzips automatically to a temp folder anyway?
