This problem affects FireFox as well since it is a problem with Adobe Flash player which is also compatible with FireFox.
There are several things to try. The fixes range from updating video and audio drivers for your system, uninstalling Adobe Flash and reinstalling, all the way up to hacking the registry. Poking around in the registry isn’t really recommended. It’s not hard to do, but it is easy to mess up.
One trick that might work is to go to the directory on your C drive called:
C:\WINDOWS\system32\Macromed\Flash
In that directory you will see a file called “flash9b.ocx”. Right click and hold on that file and drag it to the bottom of the list to make a copy of it. Once you have a copy of the file, rename the original as “flash9b.ocx.old” (add .old to the name). Now make a copy of the file “flash9.ocx” (notice this is an older file and doesn’t’ have the B in the name). Once you have made a copy of that file, rename that copy as “flash9b.ocx” (make sure to delete the orignal flash9b.ocx first so that you can rename it).
Doing this will make the system use the older, but stable flash9.ocx module instead of trying to use the flash9b.ocx module. This may or may not solve the problem. It depends on whether or not the flash upgrade added other DLLs for use.
A more stable fix that has worked for many is to edit the registry and look for the data entry that belongs to this module. In most of the cases of this problem, the data string is set to:
C:\WINDOWS\system32\Macromed\Flash\flash9b.ocx\2
Notice the \2 at the end indicating that a directory of 2 exists....and it does not. This looks to be an install error where the \2 was probably suppose to be a ,2 (comma 2) so that it was a runtime option for the module and not a directory. Deleting the \2 from that entry has fixed the problem for many others......but not 100% at this point.
You can find this entry by doing a search in regedit. Search for "flash9b.ocx".
If you want a super safe, but tedious attempt at fixing this. Completely uninstall Adobe Flash player. Reboot. Then download Flash 9 (not the latest 9b version) and install that. However, the uninstall doesn’t always clean the registry, so this can be hit or miss.
If you know how to locate and update drivers for your video and audio card, it is suggested that you do that as well.
As of now, Adobe doesn’t have a fix for this, and is having a problem duplicating it in house.
