The key is to open the task manager, select the komodo.exe process, right-click
it using the "set affinity" function.

Remove the checkmark from all but one CPU and komodo will work fine.

Thanks to community contributor JTa for working this out.

This problem is because Komodo is installed to the path

C:\Program Files (x86)\

on Windows Vista x64, and php.ini will not allow paths with parnthese characters in it. There are two possible workarounds:

1. Run the debugger configuration wizard and specify that Komodo's php.ini and php_xdebug.dll should both be placed on a safe path, preferably something like:

C:\php5.2\xdebug\

2. optionally reinstall Komodo to C:\Program Files\ instead.

The Windows command interpreter cmd.exe does not support IO redirection for programs started via shell associations, like those created for .pl files during the ActivePerl installation. It only works for .bat, .com, .cmd, and .exe files.

You need to write:

perl foo.pl | perl bar.pl

Or if the files are not in your current directory but are on the PATH:

perl -S foo.pl | perl -S bar.pl

Alternatively, you can wrap your .pl files into .bat scripts using pl2bat:

pl2bat foo.pl
pl2bat bar.pl

Then run them as:

a | b

This is also the case for > and <.

The best version of ActivePerl to use on Windows Vista is always the most recent build of ActivePerl 5.8.8 or 5.10.0.

ActivePerl 5.8.8.819 and later versions pass the same suite of tests on Windows Vista as they do on Windows XP and other supported versions of Windows.

ActivePerl's known issues on Windows Vista include:

• PerlIS and PerlEx are installed but not automatically configured due to differences in the script extension mapping process for IIS
• the OLE browser will not function with Internet Explorer 7

If you run into other issues, please report them at:

The best version of Komodo to use with Windows Vista is Komodo 4.1.1. Komodo 3.5 and earlier will not work with Vista.

Should you run into any issues, please file a bug report at:

The best version of ActivePython to use with Windows Vista is ActivePython 2.5.0.0.

ActivePython versions 2.4.3.12 and above pass all of the same tests on Vista that they do on Windows XP and other supported versions of Windows.

Note that you will need to right-click on the installation file and select "Run as Administrator" for the installation to be successful. This issue will be resolved in a future version of ActivePython.

The best version of Tcl to use with Windows Vista is ActiveTcl 8.4.14 or later.

There are currently minor issues with installing and uninstalling, but these are not serious and are being worked on. The demo applications distributed with ActiveTcl all function as expected, including the graphical libraries and Expect.

Note that you will need to right-click the installation file and select "Run as Administrator" for the installation to be successful. This will be fixed in a future release of ActiveTcl.

Go to Start | Run. Enter 'CMD' in the Open field and press Enter. This will open up a DOS command prompt. At the prompt, type:

  C:\>perl -v

You should see version information for ActivePerl.

To evaluate perl code on the command line, you can do this:

  C:\>perl -e "print \"hello world\";"

Note: you must escape double quotes in the code when using -e.

To run a script:

  C:\>perl scriptname.pl

If you are looking for an editor / development environment for Perl, you should try ActiveState's Komodo:

http://activestate.com/Products/Komodo/

1. Right-click 'My Computer' and select 'Properties'
2. Click the 'Advanced' tab, then 'Environment Variables'. This opens
   the Environment Variables dialog.
3. In the top 'User variables for ' pane, select 'PATH' and
   click 'Edit'. If there is no 'PATH' variable, click on 'New' to create
   it.
4. Add this to the beginning of the 'Variable value' field:

  C:\perl\bin;

5. Click 'Ok' to close each open dialog

You may want to open a new command prompt to check if perl is now in the
path. The following command should work (and return perl's version
information) if the above steps were successful:

  C\>perl -v
