Prep for High Sierra from El Cap and can't convert to Clover

Like the title says, I'm prepping my install for high Sierra and need to convert to Clover first. I've been on a hackintosh for several years now but rarely need to fix anything so I always have to clear the cobwebs whenever I do this so sorry for the basic questions.

The installer doc on Tonymac said to test out my clover install on a USB first before committing to it. I downloaded the installer for High Sierra from the app store but I'm getting the "incomplete installer" problem. My installer is the 19mb version. Every post about this on Tony Mac just says to read the FAQ, but it doesn't say how to fix the damn problem.

There was a post here for Sierra about modifying a file on the installer but it's not working for me.

Is there a way to force the app store to download the full version of high Sierra or get past the error in unibeast? I'm stuck.
