Runtime Error 6034

First of all, several people including many who do not even use MasterCook have had this problem. It is not specific to MasterCook. Many have found it was a result of a corrupt iTunes installation. So, the easiest thing to do to rule that out is to uninstall all Apple products from your computer. Restart your computer and see if MasterCook is able to work correctly. If MasterCook is finally working correctly then download the latest versions of your Apple software and reinstall. Apple Support recommends you remove them in this order:

Remove all of these items in the following order:

  • iTunes
  • Apple Software Update
  • Apple Mobile Device Support
  • Bonjour
  • Apple Application Support

If you receive a runtime error when you start up MasterCook 11 keep the program closed. Use Windows to browse to the Mc Tools folder on your computer. In Windows Vista or greater it will be at this location:

C:\Users\Public\Documents\MasterCook\Mc Tools

Inside the Mc Tools folder delete the MC World.mcw file. Start up MasterCook and see if that fixes the problem.

Otherwise, others have had this error message as well. The cause has been multiple copies of the msvcr80.dll file on the computer. This error message and problem happens with other programs too, as explained here:

Download and run that program after you get the error message. Another user with this same exact problem reported:

Downloaded Process Explorer. Used it to find two instances of msvcr80.dll running when I got the error. One of them was from MS and in the sxs area and the other from ATI, my graphics card supplier. The only thing I can think of is that I got an update from ATI that loaded the DLL. Deleted the ATI version and MasterCook is running normally now.

If you find multiple msvcr80.dll files on your computer, this may be the cause for you too.
