Run-time system error due to COBCONFIG

A run-time system error occurs if either the COBCONFIG or COBCONFIG_ environment variable is set when you run Enterprise Developer applications or when you use Enterprise Developer to edit or create projects and the configuration file it refers to contains entries that are not valid for Enterprise Developer.

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:

If the invalid tunable is not needed by another application, remove it from the run-time configuration file.
Add the following as the first line in the configuration file:
```
set cobconfig_error_report=false
```
Unset COBCONFIG (or COBCONFIG_) or set it to another configuration file that does not contain the invalid tunable for the particular session you are running in.

Licensing error due to environment settings (applies to Windows environments only): The message "Micro Focus License Manager service is not running" can occur when you invoke a Net Express, Mainframe Express or Studio Enterprise Edition utility from Enterprise Developer. This happens when the tool is invoked with Enterprise Developer environment settings while it requires the Net Express or Studio Enterprise Edition ones.
This happens when you edit files such as .dat that have a file association with Net Express or Studio Enterprise Edition.

Performance Monitoring Issue: Having an Enterprise Developer product and Studio Enterprise Edition 6.0 or Server Enterprise Edition 6.0 installed on the same machine, and trying to uninstall one of them, breaks performance monitoring and it is not possible to see the Enterprise Server performance counters. To resolve this problem, run the installer of the product you wish to retain on your machine, and repair the installation.
