How to setup VisualSVN post-commit hooks in win7 64bit

Question

My post-commit hook is never triggered and i think it's because
there is some filesystem permissions i need to set.

I have VisualSVN-Server-2.5.2 installed and running eclipse with Subversion pluggin.

Everything is working as expected except for the VisualSVN hook triggering.

This is my post-commit.cmd file with the name "post-commit.cmd"

C:\PROGRA~2\VISUAL~1\bin\myScript.cmd 
exit 0

UPDATE 1 when i put the "start" text like this the Commit window freezes with a pulsating progress-green bar, like it waiting for the hook triggering or somehing.I cannot
cancel commit operation but i can close eclipse and then hard-kill the commit window.

start C:\PROGRA~2\VISUAL~1\bin\post-commit.cmd
exit 0

UPDATE 2

It's working if a save the repository to local hdd. It's when save-path is for network drive that its not working. Ok that's a forward step. the bath file need some user/password maybe

Here's the bat file that saves the repository to local hdd(thanks to Christopher C. Simmons (CCS))

The idea is to launch a larger script myScript.cmd witch are doing the hotcopy of
my repository. This is working if i manually start the post-commit.cmd

reading the manual here visualsvn.com

I cannot understand what to practically do regarding this text below.

"Subversion executes hooks as the same user who owns the process that is accessing the Subversion repository. In most cases, the repository is being accessed via a Subversion server, so this user is the same user as whom the server runs on the system. The hooks themselves will need to be configured with OS-level permissions that allow that user to execute them. Also, this means that any programs or files (including the Subversion repository) accessed directly or indirectly by the hook will be accessed as the same user. In other words, be alert to potential permission-related problems that could prevent the hook from performing the tasks it is designed to perform."

UPDATE

Answer 1

• VisualSVN Server service runs under Network Service account by default or under dedicated custom account (should be created manually).

• Subversion hooks are executed under the VisualSVN Server service
  account (Network Service or dedicated account)

If the hook script works properly when you start it manually, I advise you to check the permissions for the service account. It should have access to 'C:\PROGRA~2\VISUAL~1\bin\myScript.cmd' and all other files involved.

Please also note that before Subversion calls a hook script, it removes all variables -- including %PATH% on Windows -- from the environment. Therefore, your script can only run another program if you spell out that program's absolute name.
