I tried to start Encore from the run window and held down the Ctrl and Shift keys because I found an Adobe Community post that said that would delete the preferences file. It works sometimes but usually not (wierd). And when I try to dynamically link from Premiere to Encore it always fails Encore just refuses to open. So I tried downloading and installing Microsoft Visual C++ 2010 Redistributable Package (x64) as recommended by John, again to no avail. The project I'm trying to burn is on an external drive so I took it to another computer and completed it. Pretty clearly there is nothing wrong with the Premiere or Encore files. I guess the next step is to uninstall and then re-install all of CS5 which I hate to do because it takes hours to complete.
Later -- I have now uninstalled and re-installed Encore (leaving the rest of CS% on the computer). The first time I tried to open it, it happened. Thereafter the usual message:
Runtime Error!
Program: C:\...
This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.
So I'm a bit frustrated. I've tried everything that has been suggested, including the re-install, and yet the problem persists. Help!!!!!
