Extract the psdzdata folder from your downloaded archive directly into C:\Data .
Before downloading, ensure your hardware meets these standards to prevent "bricks" during the coding process:
Search for "E-Sys 3.30.1 & E-Sys Launcher PRO 2.8.1 bundle" on forums like Bimmerpost (F80 or F30 sections). Install E-Sys: E-Sys_Setup_3.30.1.exe .
