There is little to no information on how to resolve Shockwave error 10. This error also includes a statement about files missing. (" Shockwave Error: 10. One or more Shockwave files are missing ") Un-installing and re-installing the IE plug-in doesn't help either. The method found to fix the problem was to copy files needed. In this case they were on the same computer. In your case, you may have to get them from another system. The files are located in two directories. The two directories are located in the windows system32 folder in shockwave directories under macromed (or macromedia) and adobe. One of these two directories are missing the files needed.
The first step is to run an uninstall of the shockwave player using control panel add/remove programs. for Vista and Windows 7, it's program and features. reboot if the uninstaller says to. Go to c:\windows\system32\adobe\shockwave and also open another explorer window and go to c:\windows\system32\macromed. Copy the files from the directory that has more files to the directory which has fewer. If there are not files in either, get them from another computer running the latest shoockwave player add-on.
Once the files have been populated into the directory or directories, go to a a site or THE site which you have tried to use and discovered shockwave isn't working. Don't use adobe shockwave installation site to test. In the case that I experienced this problem, the shockwave site worked but the actual site I was trying to use didn't. the site that uses the shockwave plyer will detect the player is not installed and give you the prompt to install the component. follow the short procedure to install the plug-in. If the message window has an option to trust the publisher, then check the box to always trust the publisher. Refresh the page if needed or even close the current browser window and reload the page you're trying to view that has a shockwave component in it.
