Hi John,
yes, I mean command prompt . You need to start this (run asadministrator) switch into the folder where the TREX installation binaries located (in your case this is E:\TREX\tx_trex_content\TX_WINDOWS_X86_64 )
run install.cmd --action=remove --sid=TRE
The script should delete the TRE instance. After that you need to check if the folder F:\usr\sap\TRE exists
and delete this if necessary.
After that you need to execute the script 2nd time but with different options to install the TREX:
install.cmd --action=install --sid=TRE --instance=05 --password=<Password>
f.e.
install.cmd --action=install --sid=TRE --instance=05 --password=MyPassword123!
As the MDG should use Embedded Search , the sizing guide for the TREX is valid here - you can use the notes
1249465 and 1266024 .
Best regards,
Mikhail
