PSI reported that Shockwave was out of date & needed a manual update. When I clicked on the Solution button a message box said "Unable to locate appropriate web browser for the requested URL". I clicked on the only option - OK and a second box said "An error occurred while attempting to open the specified URL". PSi provided the following info:

Program Name:
Adobe Shockwave Player 10.x

Security State:

Download Link:

Instances Found:
C:\Windows\System32\Macromed\Shockwave 10\SwOnce.dll, version:

Last System Scan (localtime):
22. Jan 2011, 09:03

Operating System:
Microsoft Windows 7,


I'm using Win 7 and IE8 with Zone Alarm Security suite (ZA is set to allow PSI and PSIa access as needed. All fully patched. Although my default browser is IE both Chrome & Firefox are on my computer.
Also when I clicked on the link from with PSI for the forum I got the same error messages.

I pasted the download link into my broweser and updated Shockwave OK.

Any ideas?

Before starting to fix Adobe Shockwave do U really require it? Windows works perfectly without this programme which may have been pre installed on the PC at the time of purchase.

If not required just uninstall it completely. If you do have a requirement read on:

1. Uninstall Shockwave for your OS from the clearly marked link here:

2. Reboot to clear out any left over ocx files.

3. Rescan using PSI. Are there any outstanding files that are insecure? These should be cleared out before proceeding to serial 4.

Note 1: At this stage,if PSI finds any elements of Shockwave in the C:\i386 folder or on any drive other than C that is an OEM reinstallation partition (normally D drive) or a drive U use solely to backup your work U can safely create an ignore rule.

Note 2: The path on the C Drive to any remaining insecurity is important. Does it point to the Shockwave Player or another Adobe product that has a Flash element? If it points to Shockwave right click on the file(s) & delete them. If it points elsewhere reinstalling Shockwave will not necessarily clear the problem.

4. Reinstall Shockwave from here:

5. If you wish to test your new Shockwave Player the link is here:

You seem to have had almost an identical problem about 2 months ago.....which you don't seem to have resolved at that time.
Here is an extract from the newer FAQ's :-

The PSI says "An error occurred while attempting to open the specified URL" when I click links. How can I solve this?
This error occurs because the registry key specifying your default browser is not properly set. To solve it, try setting your preferred browser as default again.
You can read thro' the FAQ's complete, here :- FAQ's

Hope it helps......regards,

You're right I forgot! Too much happening in life. When I looked for the key "HKEY_CLASSES_ROOT\HTTP\shell\open\command" it did not exist (and still does not) it's only down to the "open" key. Interestingly the key "HKEY_CLASSES_ROOT\htmlfile\shell\open\command" does exist. Anyway I created a new "command" key for the HTTP entry containing "C:\Program Files\Internet Explorer\IEXPLORE.EXE" -nohome and it now seems to work. Guess I wan't too sure about creating a new key last time.

Interestingly Microsft Knowledge base doesn't mention the creation of this key when you make the browser the default & it did't do it on my system. See

Thanks for the help. PSI v2 is a great pice of software & I recommend it to all my friends.

Again thanks :)
