never had any issues with compressing or installing this.
have enough freespace, or enough ram to allow process of installing ( without anything else running in background ) ?
I never use precomp as it takes way too long to decompress, almost twice as long as a regular install. Without using that double process that takes at least double the space & twice as long to install.
try reading through this page for more info, but DO NOT replace any dll files as the page suggests.

try using diskspan which is much quicker, as it doesnt split archives, which need to be joined before installing
and therfore doesnt double install time.
