Opening dng files

Question

I'm unable to open folders containing dng files in Windows 10.  The folder opens then closes straight away.  Any ideas why or what I need to do?  Thanks.

Answer 1

This is the common reason that leads to the DISM error 87 the parameter is incorrect. In most situations, users may forget to type a space before the slash when they type the command.

Just copy and past my command above. You probably forget a "space"

Answer 2

Yes I am and yes I did. It took me to the black screen where I got the above result.

Answer 3

Ok are you the administrator of this pc? if yes did you open the command prompt in admin mode as I had written?

Answer 4

Hi Marco,

Thanks for replying.

I did as you said but after each command it said "unknown" and error 87 so it didn't perform the scan.

Hello !

My name is Marco and I am an Independent Advisor. I will do my best to help you.

We can start to run the System File Checker tool (SFC.exe)

And if that doesn't solve the problem, we will test another solution

Follow these steps:

Click on windows start button, type CMD

Right click on " prompt command " and " run as admin "

Now type this commands

DISM.exe /Online /Cleanup-image /Scanhealth

Press Enter.

Then, this command and Enter.

DISM.exe /Online /Cleanup-image /Restorehealth

Then make the following commands.

sfc /scannow

When the scan is finished, check if there are any errors detected.
