Embedding a flash file (don't know version & also need to avoid PC warning dialogues): what's the latest correct way?

Question

Problem: I've had a flash Christmas card created for a client
by a designer. Before I can forward it to the client I want to
embed it in a html page for them. The designer doesn't know how to
do this (I wish I'd known before I commissioned them) and also told
me they don't know what version of Flash created the file. They
think it was 4 or 5. Eh? Whatever. I went to Adobe's site expecting
that somewhere there would be a page providing the cut and paste
code for this, but if there is such a page, it's impossible to find
by an average person! So I tried cutting and pasting some code I
found on a blog which discussed that Microsoft and created an
update that caused all sorts of dialogue windows to appear before a
flash file could be played e.g. "Click to activative this file",
but that this new code would overcome them. Whatever. Pasted the
code. Worked fine in a Mac browser, and on some PC browsers it
didn't play, or the dialogue windows appeared and had to be clicked
through before the file could be played. Am now officially tearing
my eyebrows out. Could someone very kindly please paste or direct
me to the embedding code that: plays a flash file of any version
AND which overcomes any stupid PC dialogue windows. And Adobe: not
everyone is a ******** navigational genius. Please put a link to
this information on the first page of your Support page. Asking it
as a question in the search box doesn't provide the simple
answer!

How to use Migration Assistant to transfer files from another Mac
If you only need to transfer files then connect the two via Firewire cable and use Target Disk Mode to access the old computer's hard drive from which you can select and copy the data you need.
Office 2008 will work, but it would be better to upgrade it to Office 2011. If you want a seamless changeover with respect to the iDevices, then you need to transfer the entire /Home/Library/Music/iTunes/, /Home/Library/Music/iTunes Playlists/, /Home/Library/Music/imm Media/ folders to the /Music/ folder of the new computer. Also copy over the /Home/Library/Preferences/com.apple.itunes.plist file to the /Home/Library Preferences/ folder on the new computer.
Be sure you de-authorize the old computer: iTunes Store- About authorization and deauthorization. Be sure to do this before any of the above is done.
Firewire, we don't have any of those cables and devices unless the new MacBook comes with it? It's all USB(2). Can we use USB (yes, it is slower)?  He use it for digital cameras, Time Machine backups in Mac OS X 10.5.8, etc.
OK, I will tell my client to get a new Office 2011 then to avoid the mess. Hmm, can't we just synchronize our iDevices with iTunes to copy back to the new MacBook's new HDD?
