How can you run a 32 bit version of explorer on 64 bit windows 7 x64?

This is to allow tortoisehg to work.

I've tried running "c:\windows\syswow64\explorer /separate" and it just starts another version of the 64 bit explorer.


There is no 32bit explored executable bundled with 64bit win7, so you cant.

    This answer is incorrect, except possibly the last two words. 32-bit explorer is found in typical installations at C:\Windows\SysWow64\explorer.exe

  • While the 32-bit version exists, as user26523 points out, you still can't run it. I assume it's there for library (et al) calls only. The fact that it will not run also suggest it might not actually be a full copy of explorer in the first place.

Seems like there's currently no known way of getting this to work in Windows 7 (does in Vista though) according to the answers further down here: Stackoverflow question 39746


Use the "Virtual XP Mode" addon. I am running Windows 7 64-bit and use the Cisco VPN and XP 32-bit IE for connecting to the corporate network.

  • The ShrewSoft (or other) VPN Client is a much more elegant solution.

You might be able to run 32-bit Explorer if you stop all other instances of the Explorer.exe process. Including your desktop shell. (Note that sometimes it can hang around in the background.)

  • Nope. That doesn't work.

There's a 64-bit version of TortoiseHg right on their download page:



The general rule is:

If you start a app or script from a Desktop shortcut or Windows Explorer (= 64-bit applications on 64-bit Windows!) the script runs in 64-bit mode. But if you start the same script from a 32-bit application such as Total Commander the scripts runs in 32-bit mode.

Explorer++ is the solution that worked for us to run ClearCase. All our context menu's display in explorer++ and is also useful as it has Tabs in it
