Problem:

After installation, when opening any workspace you receive the following error.

"TSUIN0126 At least one exception occurred during the initialization of the AWM meta model. See error log for more information."

Resolution:

This error can be caused by a bug in the version of Eclipse that is delivered with Visual COBOL 3.0, which may not recognize Windows Server 2016 as a valid operating system. This can be resolved by manually specifying an Operating System version that Eclipse will recognize, following these steps:

1) Open "C:\Users\Public\Micro Focus\Visual COBOL\eclipse\eclipse.ini"

2) Add the following to the bottom of the file

-Dos.name=Windows Server 2015 R2 

3) Save the file and then reload Eclipse

Note: This problem does not occur in Visual COBOL for Eclipse 4.0.
