DAX Reinstallation

Just accepted the Windows Fall Creator update on Windows 10. It completely trashed my DAX and all my bookmarks on my 6500 install. Can someone please send me the link to the procedure for reinstalling DAX, which I believe requires removing the phantom com ports? I thought that v2.x fixed the update problem? Just curious if anyone ever created a batch file to automate this situation.

G'day,
My 2.x got messed up in a new PC with the big update. DAX needed a full removal and reinstall and realocation of default sound devices.
With help of Dudley and the COM port arbiter tool I got CAT going.
I do have a batch file for ghosted com ports that makes it easier.
Paste

set devmgr_show_nonpresent_devices=1
start devmgmt.msc

Into a text file and save as a bat file and go to view hidden after running it.
You can then uninstall them.

Manually removing DAX audio devices can create bigger problems as it may not remove the registry entries associated with the driver install.

Tim, thank you! So you stated that "Manually removing DAX audio devices can create bigger problems ..." Isn't the procedure you reference above manually uninstalling and reinstalling them? And how bout removing the "ghost ports" - not required? Sorry to ask more questions, but I don't want to create a bigger problem than I already have.

Some people are under an incorrect assumption that using Device Manager to remove the audio devices is the way to remove DAX drivers and this is not the case.  The batch files do the uninstall and install of the drivers properly.

I suspect the ghosted DAX audio devices are from uninstalls using Device Manager.  Removing ghosted ports may be needed but only after the devices have been removed using the batch files and the PC has been rebooted.  Then you can redo the install.

Tim, just wanted to thank you again and let you know what was discovered.
1 Using the batch files I uninstalled and reinstalled the DAX drivers without any problem. Just had to update the version referenced in the batch file.
2 After the reboot, Dax indicated it was working, but WSJT was not seeing any audio.
3 I decided to reach out to Dave WO2X who offered to remotely log into my PC via
Team speak. What he found was interesting ....
4 The Windows Fall Creator update changed the default audio input / output devices. But even after resetting those, WSJT would not decode - though audio was reaching the software.
5 Dave also discovered that the update changed some setting in Meinberg, creating a time error. More interesting, the Windows time set would not work.
6 After reinstalling Meinberg all is now working just fine.

I thought this info might be of interest to those who were affected by the update.
Suggestion, it would be very helpful to create a batch file that would contain all the batch files you referenced. Looking forward , you’d only have to update the DAX VERSION #

There may have been reasons  you wanted to upgrade now, but if you are not aware and if you are running Windows Pro, you can delay feature updates up to a year, and quality\security updates up to 30 days.  For me that one feature makes it worth having Pro.

MS als o offers a patch to disable updates, but this could put you in jeopardy in other ways related to malicious software.
