These sorts of problems are common with Windows 7 64-bit.
Which operating system are you using? Have you tried installing the drivers and firmware from the site of drive's manufacturer rather than using the generic Windows drivers?
Thanks for the replies.
Yes, I have Windows 7 64-bit OS.
I did try to follow the instructions as per this site
I tried cleaning the registry and uninstalling the devices (BD drives), then uninstalling and reinstalling the PE software, and now not only do I get the "could not initialize disc burning engine" message twice (once for each of my two drives, I guess), but now I also get the "encountered a serious error and must close" message and the software shuts down.
The instructions from this link are only for Windows XP or Vista. The main difference I found is that this direction:
Select the UpperFilters line, and then choose Edit > Delete. Click Yes in the Confirm Key Delete dialog box.
is not possible...no Upperfilters line exists to delete, but the lower filters line does. So, I followed everything else to the letter.
I'm not really sure how to have the manufacturer's driver software override what Windows provides.
If this indeed is a common problem with Windows 7 64-bit users, I hope Adobe provides a software update to correct this fairly soon. I've been really happy with the product up until now; at this point I just find it highly frustrating. If I can't transfer my family videos to Blue-ray discs, it is not much use to me any longer.
Any additional suggestions are still welcome!
Have you tried physically removing the internal burner to see if the external still works as it did before?
Insanity is hereditary, you get it from your children
Thanks, but I don't think that's it. The external burner was getting the same error message before I installed the internal burner. I was hoping it would be able to initialize the new, internal burner once I installed it, but instead I now get the same message for each, then it encounters "a serious error" and closes, which is new.
I have Windows 7 Home Edition. According to the Microsoft website:
Windows XP Mode and Windows Virtual PC, available on Windows 7 Professional and Windows 7 Ultimate,
So, I don't think the virtual XP mode will work for my version of Windows.
