Unable to run perl script if module is not found.

1. Error

When trying to execute a perl script, I got the following error. The error shows that perl cannot find the required module.

$ perl encryptionoptin.pl
Can't locate InstalledProduct.pm in @INC (@INC contains:

2. Cause

The error is either because the module is not installed or its path is not in the @INC list.

3. Solution

3.1 Checking Directories

perl -V

3.2 Import Module
