Insufficient Disc Space red-X on Installation

FTP'd all unzipped files to a sub-directory on my Unix Apache virtual server and set permissions. Began the scripted installation sequence and didn't get past the Prerequisites (3rd) stage. All items showed to be checked in the green except for "Server Free Disc Space."

The System Inspection determined, correctly I believe, that my server account has 0.75 GB of Free Disc Space and it marked that with a red X and in red text. Instructions say don't proceed without resolving any red X issues. I've checked everywhere in the download file packet and on zen-cart.com and find all sorts of server requirements and tech specs listed -- except for server free disc space required.

In a nutshell, if Zen Cart really does need more than 0.75 GB in order to function, I certainly don't want it. Could this be a mis-read of the System Inspection by the installation script? I can see a limitation if that were saying it needed more than 0.75 MB, but requiring more than 0.75 GB is a bit much for a shopping cart software on a VS account. Please advise.

Total is no more than 25MB required...
No solution for why you are seeing this message???

Thanks, kobra. No solution cited or linked-to, and I've looked high and low on the web site, install notes, instructions and don't find any mention of a disc space minimum. If 25 mb is what it actually needs, I'll try to proceed beyond that stage despite the red X.

Matter of fact, I went ahead and clicked the "Install" button at the bottom of the System Inspection screen (something I really didn't want to allow if it really did want to claim 750+ mb or more) and it proceeded to the next page in the install script to set up the Db, so it looks like it may have been a false alarm on the free disc space bit. Thanks.
