I also experienced the same problem. I did it a more roundabout way, though it fixed. There were a few annoyances so be prepared.
I uninstalled both curse forge and overwolf with control panel, then I went to download the the installer from curseforge. It did not work, saying there was an error in the installation.
So I went and installed overwolf using the setup installation here.
I was able to install overwolf and curseforge through that. Then when I went to download modpacks such as Better Minecraft [FORGE] it worked just fine.
Just to make sure I bumped up the backup space to max.
