Install a provisional license with RTE 6.56
Install haspdinst.exe with -i command (this is provisonal license for another product with RTE 6.56)
Installation gives error “Unable to stop hasplms service”
This is though documented in 6.56 readme
-> When upgrading the Run-time Environment, ensure that it is not currently being accessed. Although the installation program can terminate applications that are accessing the Run-time, it cannot terminate running services.
Another way of installing provisional license on the same machine where already a provisional license is installed, just use provisional V2C file (instead of bundled RTE) and that can be applied through ACC (http://localhost:1947/_int_/checkin.html).
