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

Question

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?

Answer 1

In a batch script file:

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: %%
