For those (
@OGBeno ?) that want to install this on a Mac, I'm providing a quick step-by-step below. I tried loading the app into WineSkin or Wine and it didn't work, likely because of size and amount of files needed and because the engine is based on Windows 11 (too new). So a VM is the only option, I suggest using Windows 7 - newer versions struggle to run the EPC program, and XP has some problems with shared folders on Mac (which may be useful later). For Mac's with Apple Silicon (M1+) UTM is the only option, I believe.
1. Download the EPC file
@Nemesis1207 linked to above. I'd suggest the Mega download, it's quickest though you'll need to leave it up overnight most likely. Use Chrome, Safari can't download such large files.
2. Download and install the UTM app:
UTM - https://mac.getutm.app/
3. Download the Windows 7 UTM:
Windows 7 - https://mac.getutm.app/gallery/windows-7
4. Search for and download "en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso" (I'm not linking to any specific sites - Google is your friend), also search for "Windows 7 Ultimate 64-bit keys" which you'll need.
5. Place the Windows 7 UTM and the Windows 7 ISO files in a good location, and double-click the Windows 7 UTM file.
6. Under "CD/DVD" at the bottom, select the Windows 7 ISO file.
7.
Important! Click the little settings button (three sliders) in the top-right of the window, scroll down to the first "IDE Drive" and resize it to
at least 40GB from the standard 20GB. If you skip this step, the EPC install will fail. The EPC linked above installs at ~38GB, if you want to leave space for other applications (or e.g. Denso EPC) I'd suggest making it 45-50GB. Exit out of settings.
8. Press the play button, the installer should open. Press any key. Follow steps for Windows 7 install.
9. Once installed, return to the UTM window, and under "CD/DVD" select the Toyota EPC ISO file. Return to the running VM, open "my files" and find the "D:" drive which is the "disc" with the EPC. Open the "Setup" and select installation onto the "C:" disc. Follow steps. Installation will likely take hours.
10. In order to see the bottom menu options in the VM, you need to enable hiding of the taskbar (bottom bar). To do this, right-click on the task bar, "Properties", enable "auto-hide the taskbar".
Optionally, you can install Spice Tools if you want to make your VM more powerful, but this is not required to simply run the Toyota EPC.
After installation is done, you can delete the ISO's (Windows 7 & Toyota EPC).
