Install of CPS blows up on fresh Win10 install.

[K7DGF]

While trying to load my DM-1801 w/OpenGD77, I installed the R2023.04.18.01 version. The serial port driver was installed, as the serial port came up on COM5. I opened the desired codeplug I'd created several months ago, when I first bought the radio. When I attempted to either read or write the radio I get the following exception:

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.


Whats going on here? On my old machine with Win10, and an earlier version of the CPS, same codeplug, same radio, everything worked fine.

Thanks

Something is wrong with the COM port driver installation

[K7DGF]

Thanks!! I'll try removing the driver and reinstalling it..

[K7DGF]

I downloaded the com driver reinstall package, removed the resident driver, rebooted, and readded the downloaded reinstall driver. Same error. What's next?

Thanks

Is your comm port named as OpenGD77 ?

If not you may to manually name it.

Unfortunately different Windows version behave differently, and Windows its self has many bugs.
Check your .Net version(s) and try a different PC.

It definietly works on 99.9%+ of Windows 10 and Windows 11 and even Windows 7 machines.

[K7DGF]

The only .NET I see on the machine is 4.0. What version does the CPS need? If I didn't have the correct .NET, wouldn't the CPS installer
complain?

[K7DGF]

Can't try on another machine.. Don't have another machine..

[ok1mlw]

A month ago I installed OpenGD77 on my Radioddity GD77, then loaded copeplug and everything was ok.
Then I bought DM-R5 on Ali, installed OpenGD77 and uploaded codeplug from GD77, all OK.
Now I can only read the DM-R5, when I try to read the GD77 it ends up with the same error. Baofeng can be read completely normally.
I'll try installing it when I get another computer.

[K7DGF]

Since I don't have another "bare-metal" machine to test on, I installed a virtualbox Win10 vm, and get the same crash when attempting to
read or write to the radio. Just for fun, I've created a win8.1 vm and get the same crash.

Hi,
Crash or error like accesssing the usb serial port. If the host has à problem like this, VirtualBox can't do it better.

Cheers.
