[tex-live] Reinstall problem for Windows

[Zheng, Wei]

Hi all,

I once installed the Texlive2009 in my Windows 7 system and uninstalled
that using the control panel. Now I want to install it again. While I
double click the file install-tl.bat, I was told that

Can't spawn "cmd.exe": No such file or directory at
..../tlpkg/TeXLive/TLUtils.pm line 2047

I guess my uninstall was not clean, and I can not reinstall now. I saw
solutions for Linux system. Is there any solution for Windows?

Thanks a lot!
