Hello Ferrusq14
The mentioned files Setenv.bat & Startnet.cmd are files that belong to bootwiz itself. In the Templates folder we have more than 10 files that are used in bootwiz when creating configurations.
Seeing that you already was missing 1 file and after replacing it you found another file missing I fear that the current installation is corrupted (Missing files, and god knows what else you might be missing).
Thus I would go ahead and re-install the product, as it should re-generate those missing files. While re-installing you can still specify same DB and choose not to overwrite it, that way you will not use any Information stored in DB, nor will you lose your previously built configurations.
Best regards, Indrek
