A mod from Curseforge is working perfectly but launcher says missing file

So, I downloaded mods from Curseforge, and i double-checked that i had the right version. I even went into File Explorer and found the file. However, it still gives me this:
Unable to locate the Java runtime.
Error details: 0x00000000 - system: The operation completed successfully.
Filename on disk: javaw.exe
Path: C:\Users\Roman\curseforge\minecraft\Install\runtime\java-runtime-gamma\windows-x64\java-runtime-gamma\bin\javaw.exe
