What you will need to do is find the flash9.ocx file and copy it as flash.ocx.
To do this, search for the flash9.ocx file and right click it and select copy. Now just right click in a blank spot of the same folder and select paste. You will then find you have a file called Copy of Flash9.ocx in the same folder. Right click the new file and select rename and change the name to flash.ocx.
Once complete, the error should be history.
