Windows 10: dism mount of install.wim gets bad format error (header mismatch)
dism mount of install.wim gets bad format error (header mismatch)
I am attempting to use dism to mount install.wim for build 10240 (the current publicly available build), and dism gets an error 11, which is incorrect format error. dism lists the image correctly, and it is the only image in the .wim
C:\WINDOWS\system32>dism /mount-image /imagefile:c:\files\windows\install.wim /index:1 /mountdir:c:\mount
The log file has the following entries:

Anyone else encounter this error?
No, It won't work with the version publicly available. You would need the version that you purchase in order to mount.
The .wim from the media upgrade tool is compressed and doesn't work. Are you trying to use that?
Download the ISO from Tech Bench - it works just fine.
I'm downloading it now. Thanks for the TechBench ref. I'm also signed up for the Insider program, I should have guessed that the public wim image would be unusable for anything but actually upgrade/install and tried an Insider ISO. I'm doing some research work on the image, not something particularly useful.
The Retail ISO contains a MediaMeta.xml file that locks the install.wim
thus preventing Dism from using it
Good to know, thanks. I just downloaded a techbench ISO, I assume from the post by halasz that I won't have trouble with it. As I mentioned, this is not for anything terribly important.
The techbench ref is important to me, however. I'll be doing freelancing, and I'll probably be helping my customers with upgrading to Windows 10.
Thanks again to all who have commented
Just wanted to let everyone know, I just successfully mounted install.wim with Windows 7 dism. (Slow as molasses on my severely under-powered Dell Dimension 4500). Thanks so much for the tips.
So the answer is: use a copy of the ISO that is designed for install.wim to be mounted...
I was having some issues with Cortana on the recently released windows 10, so decided to run a SFC /Scan Now and DISM /Online /Cleanup-Image /restorehealth.
DISM Failed with
The source files could not be found.
I've discovered a weird issue on Windows 10x64 10525
Any solution yet?
SFC and DISM were failing after I installed Windows 10, so I formatted my hard drive and reinstalled Windows 10. SFC and DISM are still failing. With DISM, I keep getting source errors. Please help, as these errors are making Windows act...
I'm trying to repair my Windows Store, but DISM seems to refuse to work. I made an installation ISO that's the same version as mu os using the tool, but DISM still gives me a source error. I'm running 10240.
Getting this error when running DISM after a clean install:
Log file is available if anyone wants it. I looked at it but don't understand what it's saying.
