I get that error double-clicking this file on Win 2003:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Printers\Back Office Copier\DsDriver]

I'm confused, since this is just a pared-down export. What am I doing wrong?

What did you pare out? – AthomSfere Sep 5 '13 at 15:31
@AthomSfere, A bunch of settings specific to this computer that I don't want to transfer to other computers. I only want the two settings above. – Kev Sep 5 '13 at 15:32

What editor are you using? That looks like a legitimate reg file, but if you saved it in something other than Notepad you might have inadvertently added extra formatting codes.

Textpad, and it's saved as Unicode. – Kev Sep 5 '13 at 15:33
Save as (Windows/DOS) ASCII. It works fine on my Win7 and Win 2003 machines. – Rod MacPherson Sep 5 '13 at 15:36
TextPad didn't have an ASCII option but it did have ANSI, and that worked. Thanks! – Kev Sep 5 '13 at 15:37

I was having this problem as well - I had read to make sure it started with Windows Registry Editor Version 5.00 and that it was saved in ASCII or UTF-16 LE (Little Endian), but was still getting the error.

As it was though, I had a blank line before the 'Windows Registry' header - so I tried deleting that and it worked.

Not sure how I haven't run into this before (after 20 years!), unless they made the compiler less flexible at some point, or I happened to get lucky with all my regfiles.
