I was excited to see OBS Studio Portable added to PortableApps, and I finally had few minutes to give it a try on a Win7 64-bit box.
It downloaded and installed fine, but no UI appeared at all.
I had to close it using Task Manager.
I tried it several times, but same problem each time. No UI or error messages appear when running it.
The only thing that happens is that a 32-bit process named OBSPortable.exe gets launched as well as a 64-bit process named obs64.exe. But no app windows appear for OBS.
Using PortableApps launcher v17.1.1.
