Instead of starting Win7, my computer displays as message that "C:\Windows\system32\cryPTUL.dll is either not designed to run on Windows or it contains an error...." None of the fixes I found on the Win7 DVD have not cured it. System seems to boot from DVD without error. Memory diagnostic reported no errors.

Tried to re-install, but it is Upgrade media and requires a version of Windows to be running.

Do you mean logonui.exe - (Logon User Interface) and cryptui.dll? (Microsoft Trust UI Provider)
Did you spell these right?

I think the text in quotes was spelled exactly as they appeared in the error message; caps,, lower case and all. Now, I look again and this time the title of the message is "LogonUI.exe - Bad Image" and the body is "c:\Windows\System32\CRYPTUI.dll is either..." I carried this borrowed computer over to the offending machine which still has the message displayed. Yes, they are typed exactly as they appear.

The machine was upgraded from Vista to Win7 about 3 days ago. I have attempted to "Restore" to the 5 restore points since then and got the same error on each reboot.

Thanks for your interest.

Did you do a "clean" install? http://www.sevenforums.com/tutorials/1649-clean-install-windows-7-a.html?ltr=C

No, I did not want to re-install all my applications, so I chose "Upgrade."

Did I mention that when I attempt to boot into SAFE Mode I get the same error message? Not able to complete the boot.

A good version of cryptui.dll should be on the Upgrade DVD, but I have found no way to substitute it for the bad one even if I could find it. I am able to run a CMD window from the DVD, but have forgotten most of the DOS commands I once knew. Perhaps just deleting the corrupted file would render the problem "fixable" by the "Repair your copmputer" function off the DVD. It does find the Windows 7 install. The "Memory Test" option scans memory with no reported errors.

What happened to the "Repair Install" feature of previous Windows Install and Upgrade disks?

Thanks.
