Updating ezdrummer 2 and blues ezx.

In product manager, ezdrummer 2 updated.

Blues ezx sound library and midi pack does not update.

I get an error message

“A helper tool could not be installed.

The operation couldn’t be completed.

(CFErrorDomainLaunched error 9.)”

The EZDrummer forum subject

“INSTALLATION IN PRODUCT MANAGER DOES NOT WORK!”

was no help at all.

Where, When, How do I find and install whatever helper tool is needed?

Operating system: macOS Monterey (12)
