WMIC product where "name like..." - "no instances available" if run in batch file

I want to find what version of Outlook is running on specific workstations. If I manually run 

wmic /node:"hostname" product where "Name like '%Office Outlook%'" get Name

in a command line, it works. But if I run it from a batch file, it returns "No instance(s) available". I've even stripped everything else out of the batch file, so only this line is left - and I still get the same result. Am I missing something?

Solution

  • In a batch script file, escape your %s by prefacing each with another % as follows:

    wmic /node:"hostname" product where "Name like '%%Office Outlook%%'" get Name

    For proof, try next in your batch file:

    echo ON
wmic /node:"hostname" product where "Name like '%%Office Outlook%%'" get Name
pause

    You should see next ECHOed command, the same as it would be typed from command prompt:

    wmic /node:"hostname" product where "Name like '%Office Outlook%'" get Name

    Escaping Percents

    The % character has a special meaning for command line parameters and FOR parameters.
    To treat a percent in a batch script file as a regular character, double it: %%
