Whenever I try to use ChemNMR, I get an error message indicating that ChemNMR.exe cannot be found.

Whenever I try to use ChemNMR, I get an error message indicating that ChemNMR.exe cannot be found.

First, make sure that the ChemDraw application (chemdraw.exe) and the ChemNMR folder are in the same location. If you have moved ChemDraw to a different location after installation, like your desktop, ChemDraw will not be able to find ChemNMR. Instead, make a shortcut to the ChemDraw application and move the shortcut to your desktop.

If this does not help, use the Windows Find File utility (Start Menu\Find\Files or Folders)to look for a file called estimate.ini on your entire computer. If you find this file, delete it, restart your computer and retest to see if ChemNMR is working.
