Repair or delete iassdo.dll.mui

Well, I need to ask how are you reinstalling?

I will also tell you about an experience I had with a Dell install. It seems Dell had altered a file and included it in the .wim used to recover the system. Luckily it was a .inf file which I could could edit and repair. But SFC found it and gave error messages.

Your file seems to be a little more important than an .inf file, but it might be, depending on how you are reinstalling, part of a modified install.

Its a normal installing with formatting C drive

Sorry, I meant what media are you using for the reinstall. Are you recovering your system from an OEM utility, using a downloaded and burned DVD, or something else?

I am using a OS DVD for installation, and doing a fresh installation formatting c drive later on deleting windows.old files

It's really strange that you would get the same thing after re-installing.
Does the same thing happen when you run SFC /scannow in safe mode?

@ MikeHawthorne i did SFC /scannow in safe mode but the same result i will sleep only after this problem gets solved

Hi

At this point all I can tell you is that this seems to be a fairly common error.

I see lots of posts about this problem, even someone who did a full install and still had the error afterwards, before updating or installing any software.

What I haven't found is a solution in any of the posts.

If I find something I'll post it here.

Now it's off to bed.

@ mike .... Please do post it here if i am not her on this forum please email me on myshah0027@gmail.com
will be waiting for this issue to get solved Good Night

Since your system shows the file is referenced by a language pack, do you have one on your system?

I have seen other posts, as Mike has and compared the Hashes to yours and they seem to be the same. So it looks like the ones I saw are having exactly the same situation as you, unless you were the original poster in those other threads.

Just for fun, I was using an MD5 checker to check my 4 files and three of the 4 had the same MD5 Hash. I suppose the SFC does not look for a MD5 hash since SFC found no errors. So it must look for another type of Hash...

@ Saltgrass could u tell me how to use MD5 checker and the link to download it
