Internet Explorer 7 will not show Flash (swf) content
Here's the problem as I see it, with some possible workarounds for the problem.
There was a new security feature introduced with IE7 called
"Cross-Domain protection feature".

While there is very little documentation on this new feature (Cross-Domain protection), there are substantial consequences introduced by this new feature. These consequences appear to arise as a result of an unforeseen dependency on this new feature with the Local Machine Lockdown feature introduced in Windows XP SP2.
The most noteworthy of these consequences is not being able to click on a link that directly links to an object on the web such as a PDF files(.pdf), QuickTime Movie file(.mov)...or in your case, a Flash file(.swf) and have it open up directly in the Browser.
So if your link is in the form of:
the new "Cross-Domain Protection feature" will kick in and you will get a blank screen with a script error notification on the Status bar. This is radically different behavior than was the case with the IE6 and earlier
Note: IE7 is Opted into this new security feature by default, and there is no specific mechanism in "Internet Options" to Opt IE7 out of this new feature.
You can place your link:
into the Trusted Sites Zone. This should allow the SWF file to be viewed in the Browser without the Script error.
Right-click on your link:
and choose "Save target as" and save the SWF file to your Desktop. Once the file is download to the Desktop, Right-click on the file and choose button labeled "Unblock", click on the button to Unblock the file and it can then be viewed in the Browser locally by opening IE7 and clicking on File --> Open and browsing to the Flash file on your Desktop.
Tools --> Internet Options... --> Advanced -->
Remove the Checkmark in the box next to "Allow active content to
run in files on my computer"
Note: While this solution will allow the Flash file to open and play in the Browser, it creates another issue if you want to run Active content on your machine by clicking on a local HTML file with Active content.
If you find that this new Security feature is more bothersome
than any additional security it might offer, you can turn off this
feature by adding a new Registry key to your Registry.
Navigate to the following Registry Key:
Add the following sub key:
Give it a new DWORD value of:
Hope this is of some help to you,
