Error at the end of upgrading GroupShare 2020 to CU15

Hi

Normally CUs update work fine. This last one gets an error at the end of installation (before upgrading the termbases):

Could somebody help? I do not have a support contract anymore, as I went over to Trados Team, but I need to use GroupShare for termbase issues, because Trados Team does not work the way I want, and with the new Studio 2026 the GS connection is very slow. This problem was solved with CU15, but I cannot upgrade it (it works on a VM that I can restore, if the upgrade does not work).

Thank you very much for any help I can get.

Regards,

Angelo
