Problem:
If Net Express 4.0 and Net Express 5.0 are installed on the same computer is there the capability of using either 4.0 or 5.0 of Net Express.
The customer develops and distributes runtime executables, that need to run with Application Server 4.0 but would also like to use 5.0 for the clients that have upgraded to 5.0
Will the executable developed with 5.0 work with Application Server 4.0?
When Net Express is opened for a compile, Net Express 5.0 comes up.
Resolution:
It is possible to have both Net Express 4.0 and Net Express 5.0 installed on the same computer without a problem as long as the PATH, COBDIR etc., environment variables are set so that the desired compiler folder will appear first within the environment variables folder list.
If a shortcut is created on the desktop which will point to either the BIN folder of Net Express 4.0 or 5.0 as desired then it should start the correct version.
These are all compile time scenarios however.
If running an application in an Application Server environment on a system without Net Express installed then the appropriate version of Application Server must be installed.
Both Application Server 4.0 and 5.0 can be installed on the same system because they use different registry keys.
It would be best to link these applications to the Dynamic Shared run-time system so the appropriate entries will be found in the registry and not through PATH settings.
