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... TCC: Code: [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. "C:\windows\system32\xx*" 0 bytes in 0 files and 0 dirs 71,437,238,272 bytes free cmd.exe: Code: C:\>dir c:\windows\system32\xx* Volume in drive C is Core Volume Serial Number is D836-7F40 Directory of c:\windows\system32 13-Mar-10 03:04 651,824 XX3040.EXE 07-Apr-10 03:05 146,936 XXCONSOLE.EXE 07-Apr-10 03:05 911,751 XXCOPY.CHM 07-Apr-10 03:05 658,992 XXCOPY.EXE 12-Oct-04 01:24 320 XXCOPY.LIC 07-Apr-10 03:05 658,992 XXCOPYSU.EXE 07-Apr-10 03:05 93,184 XXPBAR64.EXE 7 File(s) 3,121,999 bytes 0 Dir(s) 71,437,238,272 bytes free C:\> 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. Thanks!
