Repair Install fails due to WinSetup.dll error

[EWG]

Hi all,

I've been having issues with my computer, which are detailed in the following thread:

http://www.sevenforums.com/windows-...pdate-sfc-scannow-checksur-logs-included.html

I've finally decided to bite the bullet and perform a repair install of Windows 7, 64-bit. I do have my Windows registration code, but I could not find my copy of the Windows 7 CD/DVD, so I followed the instructions in the following article to create a DVD and USB boot device:

http://www.sevenforums.com/tutorials/3413-repair-install.html

I chose the USA "Windows 7 Home Premium x64 SP1 U (media refresh) X17-58997.iso" file from Windows 7 Direct Download Links.

When trying to run setup, either from the DVD or from my USB drive, I'm getting the following error:

"Windows could not load required file WinSetup.dll. The file may be corrupt. To install Windows, restart the installation. Error code 0xC1.

Any help would be appreciated.

Thanks,
EWG

Hi EWG

Did you try using another USB port ?

You could even try to recreate the USB drive .

Manually : click on rb: type CMD inside Search programs and files . Right click on CMD under Programs (1) and choose Run as administrator . When the User Access Control window comes up click on the Yes button . Once the command prompt opens up . Path should be C:\Windows\System32>_ . Type the commands below press <ENTER> after each line .

DISKPART LIST DISK SELECT DISK 1 CLEAN CREATE PARTITION PRIMARY SELECT PARTITION 1 ACTIVE FORMAT FS=NTFS QUICK ASSIGN EXIT EXIT

   Note

Disk 1 is usually the USB drive if you have only one hard drive inside the PC

Once you have that completed copy the contents of the DVD to the USB Flash Drive .

Thanks VK. I tried using another USB port, as well as recreating/copying data to the USB drive per your suggestions, but neither made a difference. I've also tried running the install directly from the DVD, with the same result as when running from the USB drive.

You're welcome EWG

Lets try this . Lets extract the .iso using 7zip . Take a look at the link below

:ar: http://www.sevenforums.com/tutorials/170795-iso-disk-image-file-extract-desktop.html

You could create a new folder on the desktop. Right click on an empty space on the desktop choose New then click on Folder call it anything you want then copy the contents of the folder to your flash drive

Gave it a shot, but trying to run the extracted files from my desktop results in the same error.

Then download a new ISO, burn to DVD using ImgBurn at 4x speed, or write to stick using UltraISO Software To Create Bootable USB Flash Drive, formatting first.

Okay, this time I downloaded the USA "Windows 7 Home Premium x64 SP1 (old) X17-24209.iso" file from Windows 7 Direct Download Links.

I then used UltraISO to create a bootable USB flash drive, formatting first.

Unfortunately I'm still getting exactly the same error.

X17-24209.iso says Windows 7 Home Premium x64 SP1 (old). Why did you pick that one.

I've used the first one you tried successfully: Windows 7 Home Premium x64 SP1 U (media refresh) X17-58997.iso

The MD5 checksum for X17-58997.iso is: da319b5826162829c436306bebea7f0f

See if the one you downloaded matches.

 

[EWG]

I looked at the MD5 checksum of X17-58997.iso, and it appears to match what you have: da319b5826162829c436306bebea7f0f.

The reason I attempted to use X17-24209.iso is because gregrocker suggested downloading a "new" ISO before using UltraISO to create the bootable flash drive. I assumed that re-downloading X17-58997.iso would change nothing, so I tried the next closest thing...

However, just to be safe, I have created the bootable flash drive using UltraISO and the X17-58997.iso file with no change in the results.

I would be tempted to clean install on another partition.

Then you can boot into the new install and copy over anything you need.

You can get rid of the sick installation when you have done that.

I agree. Shrink C, boot the installer to create and format a partition there and try Clean Install Windows 7
