This video is to help people troubleshoot the following errors in Unity:
- Could not find Unity Package Manager local server application at [file path]. Missing files could be a result of an antivirus action or a corrupt Unity installation.
- Failed to resolve project template: Failed to decompress [file path]

Guide for a similar error - “Could not establish a connection with Unity Package Manager” / "Could not establish a connection with the Unity Package Manager local server process”

I stitched this video based on information found in several different technical support forums. Hope this helps someone! I cried several times before I got this to work.

"Program it's not all of it, but you didn't really explain or showd how to fix it, i have alot of space bc this is a new disk and a new pc, AND the text is short, "C:/UnityProject/Game"

Hey there. I am having some trouble regarding saving packages and scenes and not really understanding the differences and locations. Sounds simple but the project was an import and my boss needs me to transfer everything from Blender to Unity I can not get Creator Studio to open unless the project I am selecting is the Spatial DEMO Island. Are you open to a paid consult to help me fix this problem. basically, I need an hour of mentoring/coaching regarding file types and missing packages (not in this video) and various other problems I am running in to, and was wondering if that is something you could help with?

I have the error seen at 3:45 but for some reason when I looked in the program files folder exactly like you said it seems to say I have package manager. What do I do?

[tdawg]

[MangoGT]

감사합니다. 윈도우 방화벽에 등록한 뒤, C드라이브에 설치되어있던 2019.4.31버젼을 폴더까지 완전히 삭제했습니다. 그리고 인터넷 연결을 해제했습니다. 마지막으로 컴퓨터를 껐다 켠 뒤에 다시 설치했습니다. 해결되었습니다.
