64-bit command line apps invisible in TCC

Jul 7, 2008

I'm now using Windows 7 Ultimate x64. TC/TCC is working well, except for one oddity: the 64-bit xxcopy is invisible from TCC while it works (and can be seen) just fine from cmd.exe. So...

[C:\] [14:56]# dir c:\windows\system32\xx*

 Volume in drive C is Core           Serial number is d836:7f40
TCC: (Sys) The system cannot find the file specified.
                 0 bytes in 0 files and 0 dirs
    71,437,238,272 bytes free

Is this normal/expected functionality, something that arises from the differences between the 32 and 64-bit apps? Is there any way to access xxcopy from TCC? Unfortunately it seems 32-bit xxcopy can't be installed on a 64-bit system.

This is caused by the so-called WOW64 redirection feature of 64-bit Windows. See http://msdn.microsoft.com/en-us/library/aa384187%28VS.85%29.aspx for more info.

Try using the 64-bit version of TC/TCC, or if you must use the 32-bit version, uncheck "Win64 File System Redirection" on the Startup tab of the OPTION dialog.
