Is that part of Nero software? Did you try re-installing Nero?
Start the RUN command box. Start, type in run and choose the RUN program
Type “regsvr32 advrcntr3.dll” (without the quotes) and press Enter
A pop-up box will let you know if regsvr32 advrcntr3.dll was installed correctly.
Yes, the dll file is part of Nero. Reinstallation of the program did not restore the file. Since I just upgraded to Windows 7 my Nero program is uncompatable. I did the Run thing and it said something about make sure the binary is stored in the correct path or debug it to check for problems. Don't know how to debug.
Unfortunately, Nero 7 does not offer official support for Windows 7. If you would like to use Nero under Windows 7, you can upgrade to Nero Multimedia Suite 10 and save up to 20% compared to the regular price by visting the following page and entering your current Nero 7 serial number: http://www.nero.com/deu/store-upgrade-center.html
