[statet-users] Problems starting RJ for R 4.0.1 : JRI.jar not found

[<Klein@xxxxxxx>]

Hi,
I have problems to get R 4.0.1 running in eclipse.
I am using:
Eclipse 2019-12 
Statet 4.1
I have installed R 4.0.1, package rJava and the most recent version of rj, with R 3.6.4 R integration in eclipse 2019-12 work without problems.
When I try to start R in eclipse I get the following error (JRI.jar not found), has anyone had the same problems?
Cheers
Bastian

Launching the R Console was cancelled, because it seems starting the R engine failed.
  R environment name= R-4.0.1
  R package 'rj' path= D:\Programme\R\R-4.0.1\library\rj
