Case Sensitive Silent Switches (Parameters)

Purpose:

You are creating a custom package in PDQ Deploy and need to make sure that you've got the proper silent install parameters in place. 

Resolution: 

Though not always required, it is important to know that when using silent switches the best practice is to use in the same case as is shown by the vendor.  

/q

is different than

/Q

Also a reminder on slashes. It's easy to get confused with back slash vs. forward slash. Most (not all) switches use the forward slash /. Some parameters use a dash -. 

Lastly, be careful about spaces. A classic example is the command to extract the MSI from Adobe Reader. The command line is:

-nos_o"<path_to_extract_files>" -nos_ne

There is no space between the letter 'o' in -nos_o and the beginning of the path to extract. There is however a single space between the close quote " and the  -nos_ne.
