Premiere Pro CC2015.4 don't know Media Encoder!

Hello,

I have an Issue in Premiere Pro when I will Export Media and when I will Ingest Media for Proxys!

The Error Message is:

"Adobe Media Encoder is not installed. Download and install the application to use this feature. For more information see https: ...."

Installed is:

Premiere Pro 10.4.0.30

Media Encoder 10.4.0.26

All other Versions from Media Encoder / Premiere Pro CC2014,CC2015,CC2017,CC2019 works fine together and have not this Problem!

What is the Problem between PPro and AME?

Sending Clips from Premiere Pro CC2015.4 to AE and AU works fine and AME alone works fine to!

For Example, I can create Proxys in Media Encoder and can import and attached these in Premiere Pro.

But not from PPro via Ingest, then comes the Error Message.

And why are the CC2015.4 (2016) Versions from PPro and AME not listed in the Creative Cloud Desktop Manager like all other Versions ?

I have listed only CC2014, CC2015, CC2017, CC2018, CC2019, not CC2015.4.
