I downloaded and installed an AMD update yesterday on my desktop computer running 64-bit Windows 7 Ultimate. Everything seemed OK at first, but upon booting this morning I was notified "kdbsync.exe has stopped working". The message goes on to state: "A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is avaiable." That file is in folder C:\Program Files (x86)\AMD AVT\bin. After clearing the error message, my computer seems to run OK, but then I may not have tried to use the function involved with kdbsync.exe.
