Heads up- as of today I noticed the "Download Vcarve Pro Trial" button will download the version 11.5 installer, and there wasn't a clear option to download a different version.
With some searching I found this direct link to download version 11.0: https://storage.vectric.com/VCarveProTrialEditionV11_SetupENU.exe
Verified this link works today but it will likely break in the future...
