Unfortunately there doesn't seem to be a very elegant solution for this, but you can at least reduce it down to two mouse-clicks ... (like I said, not quite as elegant as one mouse click, but...)
*** NOTE *** I tried this on Windows XP 64-bit. I have no idea if this exact method will work on other MS 64-bit OS'.
Insert a new context menu entry in the 64-bit explorer by either:
A.
- go to [Tools] > [Folder Options] > [File Types]
- find the "Folder" file type and click on [Advanced]
- create a new entry by clicking on [New]
- Name the new entry in the Action field (I called mine Explore 32-bit)
- In the "Application used to perform action" field, enter the following command (for some reason I had to hard code the path instead of referring to the SystemRoot variable:
C:\Windows\SysWOW64\explorer.exe /separate, e/,%1
- Click [OK] to save the new entry
- OR -
B.
Copy this text into a .reg file and import it into your Windows XP x64 registry:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Explore_32-bit]
@="Explore 32-bit"
[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Folder\shell\Explore_32-bit\command]
@="C:Windows\\syswow64\\explorer.exe /separate, e/,%1"
You should now have a context menu entry in your 64-bit explorer that will allow you to open a folder in a 32-bit explorer window. So if you want to scan a specific file, right click on the folder containing the file, select [Explore 32-bit], and the folder should open in a 32-bit Explorer window, where you can then right-click on the file you want to scan and select "Scan for Viruses".
HTH.
