Error message is pretty clear to me.
If you are installing all the listed fixes it should install it. If you are installing the fix selectively, add the other components that are listed in fix recommendations or install all of them. Fixes are cumulative and softwareag recommends installing them on frequent basis. If you skipped them for a long time, take a backup then install all the available fixes.
If installing all of the available fixes and still getting this error, try to uninstall the previous fix for this product and do it again.
Another thing to verify, you have webservices stack installed in your environment right? If you don’t have the product installed, you can’t install the fixes.
