Update your Win 7 installation media

From post 1, when I follow these instructions:
1. Copy and paste your installation media to your hard drive (OK, seems easy enough to understand)
2. Right click and Run as administrator on the the 7update.cmd (OK, did that)
...The blue cmd window that opens just freaks out, flashes wildly, scrolls in high speed, and seems to be trying to flash messages about (hard to read as it's all flashing)
1. "please select the path of the windows installation file"
2. "BIN\setwimdirpath.cmd is not a recognized internal or external command"
But it's impossible to enter any text or interact with the cmd window at all now that it's freaking out. All I can do is close it again.

...is that what happens to everyone else when they try it? lol

I'm trying to get my new NVME drive to be recognized when I try to install Windows 7 x64 on it. Of course, with every new supposed fix I discover on the internet and try, I'm the only one getting the dead end results I keep seeing.
I see some have mentioned retrieving a driver from the drive's manufacturer which can be loaded via USB during the W7x64 install process. But there is no such driver referenced on the manufacturer's website. (it's a Sabrent Rocket 250GD NVME drive "SB-ROCKET-256")

The thread topic fix didn't work for me, so I used free MSI Win7 Smart Tool, which was specifically made to effortlessly integrate NVME drivers into W7 installation media. It worked!
...It also supposedly can (I didn't try this) integrate USB drivers for the new AMD CPU's that normally force you to install Windows 7 with no USB support.

Yes, I am aware of it. This tool can do much more. It is really intended to create updated installation media.

OK, NOW I'm confused.
I know this whole thread is specifically about updating installation media, because it's in the title. I also know that the MSI Win7 Smart Tool I mentioned was specifically created to update installation media. So when you say "this tool" and "is really intended to create updated installation media" I can't know for sure which tool you're talking about. I assume you're talking about the thread topic tool, but who knows.



In the end, my fix didn't really work either. The NVME drive was finally recognized with my updated installation media (created by MSI Win7 Smart Tool) during my Windows 7x64 install attempt. Problem was, it stopped right there and gave a fun new warning message about: "this drive might not be able to boot" so it would once again not allow me proceed with OS installation to my NVME drive. The warning said to make sure it's set to "AHCI" in the bios ("RAID" was my only other choice) which is definitely already is... Still, I got their tool to do stuff instead of just freaking out, so that was nice.

I finally got past the wackiness with your added instructions, thanks!

Now the resulting installation files are too massive to put on a fat32 USB stick or a DVD. So I'll now assume the installations created with this method cannot be UEFI-install capable. I tried some methods to split it, and tried a fix (Rufus) that claimed NTFS file system could work instead of FAT32 USB. Nothing worked for me. Thanks for all your help getting your extremely clever tool working for me, it clearly did run as intended in the end. It was like a fantastic Rube Goldberg machine the way it took off and did things on its own.
