In an attempt to get the unit to function in 24/96 mode, I have uninstalled the drivers and attempted to reinstall, but the reinstall cannot proceed, popping up a message that the uninstall needs to be completed.  I have the latest drivers for Win7 and tried to uninstall from Control Panel as per the instructions and also from the setup folder, to no avail.  I think perhaps something is still in the registry.  Can anyone help?

Make sure you turn the computer off and unplug the device. Then start the computer without the device connected and try uninstalling it.

If that doesn't work then run the clean all utility from Roland.  You will need to re-install any drivers for any other Roland / Edirol / Cakewalk devices after using this.
 
I've had a look round my egistry but couldn't find the keys you'd have to delete.  Hopefully that clean-all will work.
 
Remember that at 96khz you can record or playback but not both (Full Duplex) at the same time.
 
Get the Clean All utility from here...

Thanks very much, Gilly.  Neither Win7 or even Vista supported by this app.  This I have found to be typical of computer music devices over the years.   The user is constantly stuck between Windows versions and driver iterations.  I will call Roland tomorrow and see if anyone can help.

It should work.  I had to use it a couple of months ago and i'm running Win 7 32 bit.  If you have problems with it then right click on the cleanall file and choose the Windows XP SP 3 compatability.  Worth a shot.
 
 

The uninstaller doesn't work under Win7, nor does Roland's clean all under any emulation.  I have talked to Roland tech support about it, and they are thoroughly stumped.  As a user who goes back to the Turtle Beach/ CWPA 1.0 days, it has ever been thus.  If you have the latest Windows, the sound card drivers aren't ready for you.  In other words, unless I'm running XP, I'm SOL.  Caveat emptor.
   In order to get back running anything at all, I had to do a complete system restore predating the UA 25 EX driver install, which of course necessitated a complete reinstall of Sonar.  This is unacceptable, but it seems to be standard procedure in the computer music biz.  Nuts!

Hi Reilly,

I'm sorry to hear you're having problems uninstalling the drivers. Can you confirm if your UA-25 EX is an Edirol or a Cakewalk?

Cheers,

I have the same problem! 

I'm using UA-25 EX - Cakewalk by Roland.  
I have uninstalled the drivers and attempted to reinstall. 


When I try to install UA-25 EX Driver Ver. 1.0.0 i get the following message:


A problem may have occurred.


To install the driver, please execute Uninstal.exe (located in the some folder as Setup.exe) and then execute Setup.exe once again.


I've done this 4 times now and I get the same results. It feels like Im in a evil loop of some kind! 


Does anyone have a fix for this? I have no sound!

Is your UA-25 EX plugged in or unplugged when you try to install it?

I forgot to mention that, sorry.
Yes I have disconnected the USB kable. Only on the UA-25 EX though.

I don't think it will make any difference but im gonna remove the USB cable from the PC also and check when i get home. Thanks for showing interest Chappel! Much appreciated.
