Dolby App no longer opens

Topic

New Reply

Truth be told, may have never worked. Have only tried recently when a new Realtek driver appeared in windows 10 Updates.

Lenovo P51S. Windows 10 1909

Throws the following event errors:

I have removed the Realtek Device Driver (which DOES remove the Dolby folder), rebooted, reinstalled and same thing. The Control Panel app Icon is there.  The Realtek app is there, but only shows Stereo. The Realtek Properties from the Sound Control Panel has a Dolby tab with only an On/Off button. It is ON.

The DolbyDAX2DesktopUI.exe.config file shows the following:

<?xml version=”1.0″ encoding=”utf-8″?>
<configuration>
<startup>
<supportedRuntime version=”v4.0″ sku=”.NETFramework,Version=v4.5″/>
</startup>
</configuration>

Latest Realtek Audio Driver 6.0.8988.1

Ideas?

Thanks.

OK, this post is not getting a lot of love. I have posted at Lenovo and M’soft. Where would you seek the solution for this?

Been researching a lot on this. Interesting that some believe the kenelbase.dll errors can be caused by .net issues. I vaguely recall my Win 10 computer might have shown another .net error but cannot recall for sure.

I ran the .net setup verify utility today. Unfortunately there is no version of this utility for .net 4.8, but it verifies up to 4.6.1. I have the following errors, not yet researched:

.Net version detector detects .net 4.8

Reply | Quote

Where is the net version detector available?

As to version I need., I don’t know You can see errors in 4.6 posted. But that utility does not check later versions. And I always thought you only needed the latest version but find that not to be true. Seems different apps use different versions.

So would be nice if the repair tool found and fixed the issues in all versions I have/need.

I have the same “errors” and everything on my system is fine.

Good to know. Thanks.

I am further researching the repair tool. If it is portable and does not repair unless approved, I shall give it a try.

My guess is Dolby App is hard coded to a version of .net like 4.5 which I no longer have. Maybe. Maybe not.

Reply | Quote

Set a restore point, (and something had turned that off again and all older points gone!) then tried netfxrepair tool.

 

It found no errors. So, back to my theory DolbyDax2 might want a specific version. Open to other ideas, of course! Likely one of those drivers that should have never been updated.

Thanks. How did you determine it needs 4.0 as opposed to another 4 version? And if so, can that be added to what I have without disturbing what is there and is working?

I downloaded and attempted to install the second one: x86, x64 and received this notice as quite a few of my programs require different versions of .NET Framework:

——-

Details

Microsoft .NET Framework 4 is already a part of this operating system. You do not need to install the .NET Framework 4 redistributable.

Same or higher version of .NET Framework 4 has already been installed on this computer.

——–

If you already have this version, it won’t be installed. I am unable to assure you it’s not going to interfere with anything else, but it’s obvious that you require missing files, and I don’t see any other means of obtaining them.

See if a file search locates just the filenames: netmemorycache.h, netmemorycache.ini, aspnet.mof and report the directory for each if they exist.

Only in setupverifier. So not in a folder. But let me do an advanced search in appdata just in case….

Reply | Quote

Doesn;t appear they are hidden anywhere using “search my files”.

Reply | Quote

I download and ran net_setupverifier_new.zip (MajorGeeks) yielding the same warning as you. However, I have those three files located elsewhere on my system.

Do a show of all files, then run the search again. These files should show in the Windows directory.

I am beginning to suspect your problem is not with .NET Framework, but elsewhere.

I don’t have any of them in my Windows Directory. I wonder why you do with the same warnings?

I was lead to thinking .net issue by Googling “Faulting module name: KERNELBASE.dll,”

KB4578974

But I think I have paydirt here:

There is a .config file for DolbyDax21DesktopUI that says:

<?xml version=”1.0″ encoding=”utf-8″?>
<configuration>
<startup>
<supportedRuntime version=”v4.0″ sku=”.NETFramework,Version=v4.5″/>
</startup>
</configuration>

DolbyDAX2DesktopUI.exe.config

 

I am going to try to change that to 4.8 and see what happens. Might need more than that edited or maybe that will have no effect other than to provide more clues.

 

 

Reply | Quote

Cannot edit the file. Says requires permission from SYSTEM. Not sure I want to risk taking ownership.

Reply | Quote

.NET requirements are usually minimum versions, so a 4.5 app will run on 4.8.

cheers, Paul

Reply | Quote

Thanks Paul. That’s a shame In my reading I found “some” apps are hard coded to versions so was hoping. Running out of ideas on this one.

Reply | Quote

Been playing further. I think it really expects a lower version. Or possibly my .net 4.8 is corrupt, but the repair tool says its good. Maybe something here will trigger an idea?

Looks like the app has crashed, but there is nothing I can see that gives much more information than that.

I am reasonably convinced that the Dolby app requires .net 4.0 or 4.5 and does not work with 4.8.

Now, assuming that is true (and I would bet) one could wait for an Updated Lenovo driver (I should live that long) or since Windows now INCLUDES .net find some way to have BOTH 4.8 (unavoidable) AND 4.5 installed. Having a very tough time finding a way to do this.

Used to be you coul dhave as many as you liked when .net was standalone. Not so any longer. No longer in Control Panel.

Got a way to have both? I would wager quite a bit it would suddenly start working.

 

Reply | Quote

AFAIK 4.8 = 4.5 = 4, more or less.

An app requiring a specific version is because it uses things not available in previous versions. Using an earlier version will result in an error telling you so.

A crashing app is broken, or .NET is broken.

cheers, Paul

Reply | Quote

I have to disagree Paul.

Reinstalled the driver (which uninstalls and reinstalls the app) several time. .Netfx repair finds nothing. As does DISM / SFC.

It is not impossible for an app to be hard coded to a version of .net. Using things not available in previous is not the only possibility. Poor coding could be. And the nature of the errors and reports show that the lack of 4.0 or 4.5 is the likely cause. .net detector shows no 4 before 4.8/. I think it is a shoddy app coding that was written before 4.8 and Lenovo doesn’t seem to care to update it.

I have to believe that from the hours of research (a drag to be retired with time

Will be looking for a way to have 4.5 and 4.8 on the same Win 10 computer today. More if and when….
