The file may be corrupted or check for the available disk space

Hi!
 
I get the above error message when trying to upgrade from 8.1.0 build 8105 to 8109.
What is the amount of free space needed? I have 2 Gb free.
 
I have tried downloading the update file on different machines just to make sure that it isn't client related.
 
Kind regards
