For example, this might happen if you have Net Express or Studio Enterprise Edition installed and either COBCONFIG or COBCONFIG_ is set for it.
To work around this issue, ensure that Enterprise Developer is not running and then modify the configuration file by doing one of the following:
set cobconfig_error_report=false
This happens when you edit files such as .dat that have a file association with Net Express or Studio Enterprise Edition. This can also happen when invoking a utility within the Net Express or Studio Enterprise Edition products as an external tool from Enterprise Developer.
You can workaround this problem in Enterprise Developer as follows:
Set COBREG_PARSED= Call [PathToUtility] %1
Where PathToUtility is the path to the Net Express or Studio Enterprise Edition utility.
This ensures that the proper environment is established when running that tool.
