Yes, I got InvokeAI 3.0 installed on Windows 7 and it’s working fine with my new RTX 3060 card. I’m now a proper member of the PC desktop AI-ing crowd!
All a Windows 7 install needs is a slightly earlier cudart64_110.dll placed in the following locations in the InvokeAI installer folder structure:
..\env\Lib\site-packages\torchvision
..\env\Lib\site-packages\torch\lib
And then it installs and runs without any OS errors.
