DUI70.dll file error. Can't even get to log-on screen. Need help simply replacing file with a valid one from a dual boot setup.
I just recently installed Windows 7 64bit Professional on a new computer I built. I have well over 10 years of experience doing this, if that's relevant.I've read about many issues with this file, however, most people seem to be able to resolve this problem with SFC /scannow. I already tried this, albeit booting from my Windows 7 Professional DVD, as well as the /scanfile command for the particular file. This is on a dualboot system. I have a partition running Windows Vista 32bit home Edition, which is running perfectly normally. When I try to boot Windows 7, which had previously been running perfectly, I keep running into the same error. Before I get to the login screen, an error message shows up claiming the file is either corrupted or not designed to work with Windows 7. I tried replacing the faulty file from Vista, to no avail. It won't give me permission to. I also tried Windows restore from the boot disk, windows start up recovery from the boot disk, also to no avail. There is clearly an error with the file, as it shows that it's 0 bits; the file should obviously be larger than that. I simply need a way to replace the file with an uncorrupted file. I know that the file has to do with graphics, I had previously updated the graphics drivers to the newest version, restarted, and it worked flawlessly. This problem came out of nowhere. The PC: 4 GB RAM AMD Phenom II X4 965 x2 Radeon HD 5770 Crossfire setup I have not installed any 3rd party drivers or abnormal software on this build, only MS Office and Steam to play a few games that were previously working flawlessly. any help on replacing the corrupted file, especially from the Windows Vista partition, would be greatly appreciated.

This isn't really a multimedia issue, so it's possibly the wrong forum. DUI70 is a system UI framework file. On a 64bit system you probably have another copy under \windows\winsxs\amd64*dui70* - that one should work. The Vista one definitely won't work. Or you could copy it from a friend's Win7 64bit install. But this rather sounds like disk corruption - have you tried running chkdsk?

I don't see a link to the program that you said would be in your reply, am I missing it? I'll give this a try when I get home, but I'm predicting that it will still tell me that I don't have permission to change/remove/rename the file. The corrupted file is on my Windows 7 HDD I can only run my Windows Vista HDD. I can see the .dll file from Vista, but any attempts to change, remove, replace it, etc . . . I get a prompt telling me I don't have permission to do so. I'm completely unable to access it from Windows 7. Is there any way that I'd be able to replace the faulty Win 7 file from Windows Vista?

Let me clarify a little, the damaged file isn't preventing just a few software programs from running. I can't even log on to my user in Windows 7 64. It's completely broken. The only way I can access the file is A) through my other OS on my PC, which won't give me permission to replace or rename the file, or B) using the command prompt on the boot disk. Even then, I'm having trouble with it. I tried repairing the file, and it's still not working. Just to reiterate, I can't boot Windows 7 at all.

Thanks, I'm going to try this this evening. I'll check the disk for errors before I do, too. I'll let you know how it goes.
