If an error 1968 occurs in a 64 bit protected program, please ensure that the accompanying <program name>.cm file is present in the directory with the protected program, or the C:\ProgramData\<Developer ID>\<Product Code>\cm . If you specify a different destination directory when calling CMInstall.exe then you should ensure it is present in that directory.

In October 2019 Symantec made changes to it's Endpoint protection product which can cause false detections of SONAR.Heuristic.159 during protection checks in 64 bit applications. The file generating the false positive is <programname>.cm64.exe and since this is unique to each protected application may need to be submitted as a false positive by each software developer. We will assist developers with this process or undertake it on their behalf, upon request.

It is possible that other anti-virus or system protection software might incorrectly detect the <programname>.cm64.exe file as malware, so if this error occurs, please ensure that the licence file directory is excluded from any real-time decection.
