Fsuipc5 activation problem P3dv4

Recommended Posts


I recently purchased P3dV4 and being a fully registered user of the fsuipc and wide fs since Fsx, P3d etc. I'm currently having activation issues having installed a fresh version from sim market version FSUIPC5 5.12 for prepar3D V4.

1.) When I run the installer from the extracted zip file it installs ok as shown in the below image:


2.) Clicking Ok it prompts me to select and choose the type of registration, I just select the two options FSUIPC and Just enter new registration(s) shown below.


3.) Next step clicking Go ahead I insert my registration details name, email and 12 character key. Pressing enter it's returning an error message ( Sorry, this Key is not valid for FSUIPC registration) as shown below.


If I click cancel from the dialogue box above then it throws an error code shown in the image below.


I have attached the FSUIPC5 Install.log

Hi, Thomas thanks for the response no I did not obtain a new key from I didn't realise or wasn't aware fsuipc5 needs a key of its own. 

So does it mean I need to purchase a new fsuipc5 or its just obtaining a key without a new purchase?

I'm having the same problem. Purchased FSUIPC5  from Simmarket on 8 July 2019 and the installer will not recognise the key that was given. I have even cut and pasted from the invoice but no joy. WideFS registers fine with the old key but FSUIPC will not recognise the new key that was sent in July

meant to say WideFS, not Wide Server
