Unable to install Minimstreamer

[RayM87]

Trying to install Minimstreamer on a DS215j Synology NAS.
The latest version of Minimserver is installed (0.8.5.3 update 126) and I have Minimwatch installed on my PC.
I go to to Minimwatch, option, properties, packages and Minimstreamer is not listed in available packages. So I find the current version of Minimstreamer 0.7.10 and type that into other package. After clicking install I get the message that Minimstreamer requires Minimserver 8.3 to run. I am on Minimserver 0.8.5.3 update 126.
Im stuck and would appreciate any help.
Regards
