IE6SP2 / IE7 swf fix

Question

I found the following MSDN registry fix which resolved the
issue of IE7 not loading (viewing) .swf flash files. I accomplished
BOTH registry changes, however the second one fixed the problem. As
indicated below MSDN will have a follow up KN article on this
issue. This is an IE7 Security issue not present in previous
versions. Here is a link to the MSDN Internet Explorer Developement
forum. I used iexplore.exe as the process name for both reg edits.

I suggest Adobe look into this. There are hundreds of
inqueries/blogs online and this is the only fix I have found. I
posted here to get the widest distribution.

A KB article is coming out shortly about this issue. However,
here's the short version:
This error is occurring because of an unforeseen dependency
between an IE6 XPSP2 security feature (Local Machine Zone Lockdown)
and a new IE7 security feature designed to protect users from
improper cross-domain access to their local file system. Until the
dependency is corrected, users may correct the problem through one
of two possible workarounds (below).
Workaround:
Two options are available—each option has a potential
side-effect. The first option is to opt-in the 3rd party
application into the Local Machine Zone Lockdown feature control
key. This is the recommended option. It allows the 3rd party
application experiencing the problem to be more secure by
tightening restrictions on several URL actions that make the local
file system zone more protected than the Internet Zone (this has
potential compatibility implications). Users should read
Compatibility in IE6 for Windows XP SP2 under the section Local
Machine Zone Lockdown, for more information.
To opt-in to Local Machine Zone Lockdown:
1. Click “Start”, “Run”.
2. Enter “regedit”
3. Find and select the following registry entry:
HKEY_LOCAL_MACHINE
SOFTWARE
Microsoft
Internet Explorer
MAIN
FeatureControl
FEATURE_LOCALMACHINE_LOCKDOWN
4. Click “Edit”, “New”, and
“DWORD”
5. The name should be set to the process name of the
application experiencing the problem. For example, if the
application is mybrowser.exe, then enter
“mybrowser.exe” (without the quotes)
6. The Value (double-click on the newly created entry) should
be set to “1” (this opts the process into this feature,
enabling the workaround)
7. Close the Registry Editor
8. Close all open instances of the affected process (and IE)
and restart the program.
The second option is to opt-out of the new cross-domain
protection feature (which blocks access to scripts on the local
file system). Opting your application out of this feature leaves it
vulnerable to web sites that may scan your computer looking for
script files or other information. If your application is designed
to host arbitrary content, this option is not recommended.
To opt-out of the cross-domain protection feature:
1. Click “Start”, “Run”.
2. Enter “regedit”
3. Find and select the following registry entry:
HKEY_LOCAL_MACHINE
SOFTWARE
Microsoft
Internet Explorer
MAIN
FeatureControl
4. Click “Edit”, “New”, and
“Key”
5. Enter FEATURE_BLOCK_LMZ_SCRIPT
6. Next, click “Edit”, “New”, and
“DWORD”
7. The name should be set to the process name of the
application experiencing the problem. For example, if the
application is mybrowser.exe, then enter
“mybrowser.exe” (without the quotes)
8. The Value (double-click on the newly created entry) should
be set to “0” (this opts the process out of this
feature, enabling the workaround)
9. Close the Registry Editor
10. Close all open instances of the affected process (and IE)
and restart the program.

Answer 1

The 'iframe fix' is only a fix to get the ReadURL function to
work
properly in IE7, largely in relation to
ReadURL("javascript...")
functions > and those largely for SCORM communication.
Is that the problem you're having with your A'ware
application and IE7
or is the issue more 'getting the piece to play' at all? If
not the
former, then the iframe approach likely won't help.
What specific problems are you having with the application
playing in IE7?
