Teststand 2019 does not show PushOk as SCC

Edit : after installing the 32bit Plugin instaead of 64bit, i can select
Push-OK in Teststand, but all menue entries for "Source control" remain
disabled, and the configApp still seems to be unregistered ...tried trwice
after change to 32bit

Hi,
just installed eval of PushOK SVN SCC Plugin, but even after registration
the tool cannot be selected in Teststand.
Tortoise SVN=64bit, 1.7.15
PushOK = 64bit 1.7.13
Teststand 2019=64bit
Path to Tortoise GUI checked

The ConfigApp still shows "update registration", although did it twice on
two different PC and Message "succesful regsitered"
Trying to use SVN Tool reesults in "cannot create SVNclient" - no shure if
this points to a solution


any sugestions?

best regards
Klaus
