problem with update 7.0.6 download

Hi
I’m running the latest update 7.0.6 from current downloads
Keeps erroring with
“An installation package for the Product Cubase 7 64bit cannot be found. Try the installation again using a valid copy of the installation package ‘Cubase7_64bit.msi’”
This msi is on my system as I have a valid installed version 7. Not sure why it thinks its missing
PS I had an earlier error with permissions updating PDF docs but I just moved them out of the way.

Help
Tom

Hi
anyone ever had this problem
Was thinking of going for 7.5 upgrade but not sure it will work if patch update is failing
