AWC or CWC Mistral calculation file failing to open when when double clicked.
This may be due to the Windows computer Operating System not understanding how the file name was composed.
Characters such as brackets '(', ')' Question marks '?', forward slashes '/' and backslashes '\' should all be avoided when creating file names.
If you have created AWC or CWC file names with any of these characters then it is recommended that you change the file name.
If double clicking did not work try using this button instead
