CIC is installed in Online mode (Machine with Internet Access but no access to mdb database. It is using a local h2 database.).
When downloading a intelliRollup Security patch (ex: CA - Office 32Bit - Security IntelliRollup v1901.00), it remains in status Downloading forever.
This problem occurs when there are some patches wich are part of the Security Rollup which are in status "Exported".
Status "Exported" is not interpreted correctly by CIC Online.
Open a case at CA Technical Support to get the fix T6FX006.
