Hmm -- there's some odd permissions there...
Here's my output (Win7 Pro x64)...
Code:
C:\Windows\system32>icacls c:\windows\syswow64

                    NT SERVICE\TrustedInstaller:(CI)(IO)(F)

I need to check a few things before I start messing with anything - but I don't think it should cause a problem if you want to leave things as they are.

No corrupt files. Everything seems to be working fine. Permissions are still the same on the syswow64 folder. Is that something I should try to fix or just leave it the way it is? Thanks again!

With a bit of luck it should be fairly simple to fix...

Open an Elevated Command Prompt and run the following commands.

Code:
 
TAKEOWN /F C:\Windows\SysWOW64 /A
ICACLS C:\Windows\SysWOW64 /remove Administrators
ICACLS C:\Windows\SysWOW64 /grant Administrators:(M)
ICACLS C:\Windows\SysWOW64 /grant Administrators:(OI)(CI)(IO)(F)
ICACLS C:\Windows\SysWOW64 /remove "NT AUTHORITY\SYSTEM"
ICACLS C:\Windows\SysWOW64 /grant "NT AUTHORITY\SYSTEM":(M)
ICACLS C:\Windows\SysWOW64 /grant "NT AUTHORITY\SYSTEM":(OI)(CI)(IO)(F)
ICACLS C:\Windows\SysWOW64 /remove Users
ICACLS C:\Windows\SysWOW64 /grant Users:(OI)(CI)(IO)(GR,GE)
ICACLS C:\Windows\SysWOW64 /grant Users:(RX)
ICACLS C:\Windows\SysWOW64 /remove "NT SERVICE\TrustedInstaller"
ICACLS C:\Windows\SysWOW64 /grant "NT SERVICE\TrustedInstaller":(F)
ICACLS C:\Windows\SysWOW64 /grant "NT SERVICE\TrustedInstaller":(OI)(CI)(IO)(F)
ICACLS C:\Windows\SysWOW64
ICACLS C:\Windows\SysWOW64 /setowner "NT SERVICE\TrustedInstaller"
 
.
Post the results, and reboot

Hmm - don't know why that last command failed?
Try it manually from Windows Explorer...

Open Explorer, and navigate to the Windows folder.
Find the SysWOW64 folder entry and Right-click on it - select Properties
In the popup, select the Security tab
Click on the Advanced button
Click on the Owner tab (it should show Administrators as the owner)
Click on the Edit... button and accept the UAC warnings if any
Click on the 'Other users or groups...' button

In the entry box, type
NT SERVICE\TrustedInstaller
and click on 'Check Names' - the entry should be corrected to simply TrustedInstaller, and underlined.

Click OK once
now put a tick in the 'Replace owner on subcontainers.. box, and click OK out to Explorer.

Do you get any error messages?

Interesting that the CMD interface failed, but the GUI one succeeded - you should be good to go now.
Keep an ye on the next few Windows update installs, as if there are any problems, that where it's likely to show up first.
