Wildcards in file names are not supported in simple signatures created in BigFix Inventory Catalog Customization.
It you need to create a signature that uses wildcards in file name, you should create an extended signature. BigFix Inventory documentation contains information on how to create extended signatures as well as examples (templates) for most common use cases. You will fill this information at this link https://help.hcltechsw.com/bigfix/10.0/inventory/Inventory/softinv/r_extended_signatures.html
For your case you should use a template for a file name and the signature would look like that:
<Variable name="IS_INSTALLED" export="true">
<Compare type="string" relation="ne">
