Fix file association error in Windows 7

I’m having this very strange Perl scripts association issue in Windows 7 that is causing my automation to fail with strange warnings. Perl script launches correctly but doesn’t detect any parameters passed into it.

To fix this, I had to remove some keys in RegEdit.exe to reset the association.

Go to “Start button” -> search for -> “regedit”, and delete the following:
HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts.pl
HKEY_CLASSES_ROOT.pl
HKEY_CLASSES_ROOTpl_auto_file

Hope this helps people with the same problem.
