How to set datadir for htags in winXP

Hi,

I am using windows XP sp2. Apache 2.0.63 has been installed and run
correctly.  I downloaded glo561wb.zip and unzipped it to c:\global.

The path to two important files:
c:\global\share\gtags\global.cgi.tmpl
c:\global\share\gtags\gtags.conf

I like to have search and hypertext feature, So, I set
GTAGSCONF=c:\global\share\gtags\gtags.conf
to my system environment. and added c:\global\bin to my environment path

I also edited gtags.conf, added
:datadir=c\:/global/share\
to htags configuration

After all these done, I ran
gtags -v (No problem here)

then
htags -aDfFnv

I got error like this in console

c:\GLOBAL_test>htags -aDfFnv
[Sun Mar 16 15:33:07 China Standard Time 2008] Htags started
[Sun Mar 16 15:33:07 China Standard Time 2008] (0) making directories ...
[Sun Mar 16 15:33:07 China Standard Time 2008] (1) making CGI program ...
htags: skeleton file 'c:/global/share   /gtags/global.cgi.tmpl' not found.

Seems something wrong with the path to htags's datadir. How I should
do to solve this problem?

Thanks in advance!

Could you give me some hints where I did wrong, how I can solve this problem?
