Cannot run Phyrox-Dev 81 and Phyrox 80 at same time

[Alex9001]

Behaviour

Steps to reproduce this issue

1. Download Phyrox-Dev 81
2. Download Phyrox-80
3. Run side by side, only one loads.
4. Phyrox-Dev 80 + Phyrox 80 work side by side

Expected behaviour

Both should work at the same time

Actual behaviour

If Phyrox-Dev is loaded first, loading Phyrox just opens another dev window. And vice-versa.
