How I sorta solved my Mountain Lion download problem

[struggle4progress]

Lots of folk have been having problems downloading Mountain Lion

I got the corrupt file error from the appstore

The way I fixed this was some combo of the following:

(1) look in console for the name of the directory in /var/folders that's causing the problem and delete it (mine was /73). if you don't wan't to delete the whole folder insider of /var/folders, track down the path to /var/folders/.../com.apple.appstore and delete from there. This stuff seems to get recreated on relaunch of appstore so no biggie. Save a backup if you're nervous

(2) repair permissions on disk

(3) reboot

(4) disable anti-virus software

Downloading now, and it's a big download that takes a long time
