EasyPLC connection error

[fredz0003]

Good day,

I am receiving the following Message: PLCSim connection ERROR, code: -2147220991 even though PLCSim is running before I launch EasyPLC.

Anyone else is having the same issue?

[fredz0003]

I updated to latest EasyPLC, and latest MachSim, and now I get this error when going to the S7_PLCSim hardware on easyPLC. Is there an update to S7PLCSim driver, now is not even on my Hardware devices options?

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.

Indeed, from EasyPLC version 5.7 all the drivers have been updated due the upgrade to the .NET 4 framework.
Then EasyPLC from version 5.7, do not work with previous drivers.

Ok so it is best to just stay on 5.7, I didn't see any emails on Step7PLCSim driver so I assume is not out yet.

I think I remember there was a discussion a while back about a new step7PLC driver.
