wow64.dll Corruption - from Aug 2011 Windows 7 Patches ?
After a late August 2011 patch update to Windows 7, nothing would run, due to an apparent corruption of wow64.dll. I restored my system back to 18 August and everything worked. When I updated the system with Microsoft patches, the problem reappeared.
Now, I don't even think a complete system wipe will fix it, because it would just reappear when I update the patches.
Of course, I have a fresh copy of wow64.dll available, but Window no longer lets even an administrator replace a dll. What's up with THAT??
Anybody got any ideas? (Besides never update this machine?)
Error message (appears 3x at boot, and whenever running any 32-bit program, which is most of them):
( X ) C:\Windows\SYSTEM32\wow64.dll is either not designed to run on Windows or it contains an error. Try installing the program again using the original installation media or contact your system administrator or the software vendor for support.

Hi,
Wow64.dll is an essential file component of Microsoft windows Operating System. It allows the interior emulation infrastructure for the entry-point functions
of Ntoskrnl.exe. Wow64.dll is a 64bit Windows file that needed to play 32bit Windows program.
You can try to back up the wow64.dll to USB drive, after finish updating, replace this file, and open CMD with administrator, run
regsvr32 /s wow64.dll
Furthermore, you can run sfc /scannow to check if any system file was corrupted.
Regards,
Leo
