bin/winapps check OK, but ./installer.sh NOT OK

Hi, I don't understand why but `bin/winapps check` is fully OK (login OK, I see the entire Windows desktop trough xfreerdp), but when I run ./installer.sh it ends saying this :
```
[t0mux@tag-bureau winapps]$ ./installer.sh --user
Removing any old configurations...
Installing...
Checking for installed apps in RDP machine (this may take a while)... Finished.

The RDP connection failed to connect or run. Please confirm FreeRDP can connect with:
bin/winapps check

If it cannot connect, this is most likely due to:
- You need to accept the security cert the first time you connect (with 'check')
- Not enabling RDP in the Windows VM
- Not being able to connect to the IP of the VM
- Incorrect user credentials in winapps.conf
- Not merging install/RDPApps.reg into the VM
```

Everything seems OK and well configured, but still doesn't work. I even renamed my virtual machine 'RDPWindows' and set the Windows hostname to 'RDPWindows', no change.
Here is my .config/winapps/winapps.conf :
```
RDP_USER="administrator"
RDP_PASS="MyPassword"
RDP_IP="192.168.122.65"
RDP_FLAGS="/cert-ignore"
MULTIMON="false"
```

I already merged RDPApps.reg, and even checked if the keys are set in the registry, it's okay.

I also tried a manual start with `bin/winapps manual "C:\Program Files\Microsoft Office\root\Office16\OUTLOOK.EXE"` and it works partially... it's weird : xfreerdp shows up and login, I see the desktop, but nothing more is happening ! Outlook doesn't start ! (But it does if I just double click on OUTLOOK.EXE)
