Close your console windows(s) and open new ones.

Consoles open prior to the installation will not have the Perl/bin directory in the path. New sessions will (assuming you left that option checked!).

I think, a reboot isn't necessary if you are adding it manually.

Try

cd C:\Perl\bin
perl -v
[download]

For the benefit of the OP, if the OP didn't install with admin privileges, then c:/bin/perl might not have been added to the PATH, and the above commands will tell you if perl is installed at all (as a default ActivePerl installation). In which case you can create a shortcut similar to what is described in bart's journal to adjust the path before getting to the command line.

Also, the OP should mention that this question has already been asked.

A Google Search seems to testify to that end...

BrowserUK has it right. I've done this a bizillion times, starting with Win95. System environment variables are "inherited" by a command shell and not updated in any way, so you just have to close it and open a new one. Once ActivePerl is installed, you can verify the path this way:

In a newly opened command shell, type "path" to list the current path.

In the Windows system:


1. Right-click on the Computer icon.
2. Select Properties.
3. Select the Advanced tab (depends on version of Windows).
4. Click the Environment Variables button. Look for the PATH entry.

No reboots necessary.
