Hi, Tony, there was a problem in the installer - please see this post: It has been corrected. Please download the updated installer and try again. Sorry for this. John

If that is your issue (different name and/or email), it should now be fixed in the latest installer. Please download and try again. John

Different name/address for the different keys? If so, see my previous post....

Are you both using a different name and/or email address for each product? If so, I can see the problem and will fix it shortly. The installer is also writing the WideFS name/address to the key file for FSUIPC6 instead of the correct ones. You can manually change this by editing your FSUIPC6.key file, and put the correct Name and Address for FSUIPC6. Otherwise, I'll upload a new installer shortly with this corrected. Sorry about this.... John

Could you let me know your order numbers (not other details please - I can retrieve them!) and I'll check your keys here...

Are you entering both FSUIPC6 and WIDEFS keys and clicking the 'Register' button? If you do this, you should get two pop-ups, confirming registration success or otherwise for each key. What do you see? It doesn't matter - it will just remove and re-install. There were some changes made to the installer earlier today, to handle WideFS registration without FSUIPC6 registration. I've just checked here and registering just one or the other seems to be functioning correctly. Could you try downloading the latest installer and running again please. Thanks, John

If thats a message from the add-on, then you need the support of the add-on provider. Is FSUIPC4 installed correctly - can you see it in your Add-on menu? One thing to note is that if your sim is started with admin privileges (as it usually is if installed in your Programs folder), then any 3rd party software that communicates with FSUIPC must also be started with the same privileges, otherwise it cannot connect. John

FSUIPC6 is now available for purchase... John

Sorry, not possible. It should be available via SimMarket later today, please be patient.... John

Please see the installation manual for details on what is installed and where. When you uninstall FSUIPC5 it will remove the documents installed by that version. As you have expanded the Lua examples, it will not pick this up so will not remove these and therefore not remove the FSUIPC documents folder that is under your Modules folder. You can manually remove this if you like. For FSUIPC6, documents are now installed in your Windows 'Documents' folder, in a subfolder called FSUIPC6. John

I've now updated (and uploaded) the installer to allow you to only register WideFS7. I'd still like to update it to make it easier to use, maybe by pre-populating the details if the installer finds an existing key file, but that will have to wait until things have calmed down a bit.... John

For the time being, I've updated the Installation manual to include details of how to register WideFS7 without an FSUIPC6 key. As I said, I will correct the installer for this use-case over the coming days. Sorry that I missed this! Regards, John

Thanks Pete, was just about to look into this but you beat me to it!

Keys for WideFS7 are valid for FSUIPC6, so no need to re-purchase. John

First, you are hijacking an unrelated post - in future please create a new topic if there isn't an existing (newish) topic that is relevant. Well, that depends upon your problem! You install FSUIPC4 in the sim, and you can install before or after you install your 737NG. Folks are using FSUIPC4 with the iFly 7s7NG (e.g. see You can always download and install an unregistered version. Then take a look at the provided documents to see the extra facilities provided by registration to determine if you would like to purchase a license or not (as no refunds are given). John

Yes, sorry. You should be able to register your WideFS7 license without having an FSUIPC6 key. I will update the installer to allow this. Glad you found the solution though! John

First, you posted in the FAQ section. Please always request support via the main Support forum. I have moved your post for you. You can download from here: FSUIPC4.zip So you have downloaded it and ran the installer? To register, you need to use all 3 details (name, email address, key) EXACTLY as specified in your simmarket account - copy and paste to be sure. There have been no changes in FSUIPC4 since February 2018, so its probably the same version. Not sure what you mean by this...the installer won't copy the dll if you have the same or a later version already installed. Note that if you are running the new FSX-SE beta, you should read this post: and maybe also this: John

Hi Vic, please see the installation manual which comes in the zip with the installer - it should answer all your questions. Basically you have several options: - you can keep your FSUIPC5 installation for P3Dv4, and just install FSUIPC6 for P3Dv5, in which case you can copy across and rename your .ini file, as well as any macro, lua or other auxiliary files that you use - you can install a single copy of FSUIPC6 for both sims. If you do this, FSUIPC5 will be uninstalled but you settings will be preserved. You can choose to install in the same directory as you FSUIPC5 installation, in which case you just need to rename your FSUIPC5.ini file to FSUIPC6.ini, If you choose another directory (which is recommended), then you need to move and rename your .ini as well as move any other macro, lua, etc files - you can install separate copies of FSUIPC6 for each sim; do this by running the installer twice, and selecting to install into one of the sims when you do. Preserve or copy your settings by copying and renaming your ini, as above. Cheers, John

Hi Joe, yes, it should be possible to re-map them, and relatively straightforward if you are using the JoyLetters facility (see the User manual if you are not familiar). If you could post your .ini. .log and .Joyscan.csv files I'll take a look for you. Cheers, John

offset 3308 will contain the same value for P3Dv5 as P3Dv4 - 12 (for P3D 64-bit). You can use offsets 3304 and 3124 to determine the FSUIPC or P3D versions respectively, if needed. Cheers, John

It isn't. What makes you think that? Have you read that post? Its not free for ANY user (ie. a registered copy), BUT I will supply a new key free of charge to those users who have purchased FSUIPC5 on or after 1st Feb 2020, offer lasting until the end of May. keys for WideFS7 are still valid for FSUIPC6. John

Yes, please re-read that post - here's the pertinent section: For those users who have recently (i.e. on or after 1st February 2020) purchased FSUIPC5 but will be updating to P3Dv5, I will supply a free license if you PM (or email) me your registration details (order number and date). As always, PLEASE DO NOT publish your key details in any public forum (or your key will be banned). This free upgrade offer is valid until the end of May 2020 only.

Glad its working for you now Pete - if your happy, I'm happy! Strange about the crash though, but if its now working I wouldn't worry. Cheers, John

Hi Peter, That is strange - are you using the same ini file (renamed of course)? I doubt it, as it is working in P3Dv4.5. I don't know - maybe. You shouldn't need SPAD for throttle quadrants - only the switch, radio and instrument panels would require SPAD (or SPAD.next). Do you have the saitek drivers and software installed? If so, best to remove them. If you aren't using the same .ini file as for P3Dv4.5, then try that first (copy your FSUIPC5.ini to FSUIPC4.ini and move it from your P3Dv4 Modules directory to your FSX one). Also, if you are using an add-on aircraft, please also try with a default one to see if you get the same results. If its still not working, post your .ini and .log files and I'll take a look. Cheers, John

There should be a copy of the installer log in a file in the same folder as the installer (if you can't see the .log extension, you may have to disable the hiding of this file type via the Explorer options). Note that if you have installed the latest FSX-SE beta then please see this pinned post: Its not clear from that post, but I think you need to install the non-beta first before installing FSUIPC4, then upgrade to the latest beta and download and use the special dll that supports the beta. Please see the following post for further details: If thats not your issue, then please attach your installer log.
