The sole comment on the download page reported the app wouldn't run with an error message: VTubeGo.exe - Entry Point Not Found
The procedure entry point PssQuerySnapshot could not be located in the dynamic link library KERNAL32.dll . At the moment it shows 30 upvotes, so I took a quick look...
No problems running the app as reported by Glenn S. earlier. Monitored installation in my Win11 25H2 VM, where Process Explorer didn't show anything suspect or unusual regarding the dll files etc. used when the app was running. It uses the Microsoft C/C++ runtimes which are included in the program's folder rather than installed in Windows. It uses the QT app dev framework, ffmpeg libraries, and includes Python code libraries in the program's folder, which holds 276MB, 2003 files, & 170 folders. An additional 2 folders are added to Users\ [UserName]\ AppData\ Local\, while Windows registry gets one new key with the path to the app, and one new key for uninstall.
