When configuring Metering in a Product (Edit or create new Software Product under Manage > Software Catalog) if we put in a file name, such as winproj.exe, and check the box to "Show all Program Files", the process hangs for 15 to 25 minutes before the files will show. This happens for new or an existing product, and is consistent.
This is a known issue.
This issue is fixed in both 8.1 and 8.5 versions. Upgrade to resolve this issue.
