Internet Explorer users receive this message if the required file, acme.dll, is missing from the directory that contains the Web runtime control. Users should place a copy of acme.dll, the executable (acugtax.ocx), the license file, and ajpg32.dll in the Web runtime directory, and then try to use the Web runtime again. These files can be found in the AcuGT\bin directory on the ACUCOBOL-GT distribution media, and they are part of the CAB file distribution. You can get more information using the Web runtime AcuGetLastError method.
