Win 7 works fine of course.


I'm a little baffled how OS version affects a simple file copy, but it does.
Ah, yes. I had a similar problem with an SD card in Win 8.1 (not 8.0) on another product. The product wouldn't boot from an SD card once Win 8.1 had written to it. In my case, the product gave me a nasty message telling me that the card needed to be completely erased before the product could use it.

Here's what I learned:

Windows 8.1 creates a directory and file "\System Volume Information\IndexerVolumeGuid" on SD cards (and likely the Epson update memory block). The folder is hidden, but you can see the file by opening Windows Explorer and manually entering the directory in the location bar (and enabling the viewing of hidden files).

Their presence (on the SD card or the embedded equipment memory) seems to confuse some products.

You can remove the directory and file from the command prompt (or a batch file) with the following commands (for an SD card or USB link to the projector memory in drive F: in this example):

del "F:\System Volume Information\IndexerVolumeGuid"
rmdir "F:\System Volume Information"

The update file should then be accepted by the projector. Better is to use a PC that doesn't run Windows 8.1...like you did.

I would be willing to bet that it's a USB 3.0 issue. When doing the update, check to see if you're plugged into a USB 3.0 slot. Try a USB 2.0 slot, if you have one available. Sometimes, there are issues when using USB 2.0 devices in a USB 3.0 slot.

Thanks, that makes sense.

That actually makes more sense. The drivers for USB 2.0 backward compatibility would cause some problems if the SPD chip in the projector wasn't coded for it. Should work though. I used a 2.0 USB port in my laptop.
