Where you install P3Dv5 doesn't matter. The message means that it cannot find the P3D registry keys, which the installer uses to determine where your installation is. Did you run P3Dv5? If not, please do that first - just start it then exit. Then try to install FSUIPC6. If you still get the issue, you will need to uninstall and re-install the client.

On page 28. Basically you: - program one action in FSUIPC and close - open your ini file and find the line corresponding to that action. Copy that line. - Go back into the FSUIPC button or key tab (depending on what you are programming it for), and re-program the key/button for you second action and close. This will replace the first action you programmed. - open your ini again and paste the line you copied in step 2, directly after the new action for that key/button - adjust the numbers n (in 'n=...') so that they consecutively increment - open FSUIPC again, got to the buttons or keys tab, and click the 'Reload all ...' button to force reloading of your modified ini

...Pete just beat me to it! I would just add that, if the normal Master Battery control toggles the battery but doesn't change the UI, you can send both the control and the lvar toggle by making the button press operate more than one action. This requires editing the .ini file and is explained in the Advanced User manual. However, it would be easier to use a mouse-macro, as Pete says. John

If you have read the installation manual, you did not understand it. If you select to install in both v4 and v5, it will create ONE installation for both versions (i.e it will be shared). If you want separate installations for each version, then you have to run the installer twice, once for each sim version. As you previously had FSUIPC5 installed, and you selected to install FSUIPC6, it will first uninstall FSUIPC5. The installation folder for FSUIPC6 will default to the previous installation location, i.e. the P3Dv4 Modules folder. If you do not change this, this is where FSUIPC6 will be installed for use by BOTH simulators. No-one is forcing you yo use FSUIPC6 with P3Dv4. You can continue to use FSUIPC5 with P3Dv4 if you like, and just use FSUIPC6 with P3Dv5. FSUIPC6 just gives you the possibility to have ONE installation for both P3Dv4 and P3Dv5. You can have two installations, one for each sim version if you prefer, or just use FSUIPC6 for P3Dv5 and keep your FSUIPC5 installation for P3Dv4. It is not mentioned in the documentation as this does nothing. Your FSUIPC5.ini will not be recognised by FSUIPC6 - as I keep saying, you need to rename this to FSUIPC6.ini. FSUIPC5.ini is for FSUIPC5 ONLY. I am just repeating myself over and over again here, and also just repeating what is in the installation manual. I suggest you read this again. If you have a different issue, please raise a new topic. I am closing this topic now as I cannot spend more time repeating to you what is already in the documentation.

Have you read the Installation guide, as I have mentioned several times? The new installer will uninstall FSUIPC5 IF you select to install FSUIPC6 for P3Dv4 and you already have FSUIPC5 installed. If you only install for P3Dv5, it will not touch your FSUIPC5 installation. You can also install one version of FSUIPC6 for use by both P3Dv4 and P3Dv5, or you can have two distinct installations, one for each sim. It's really up to you. When you install, you also choose the installation directory. The folder you select is where FSUIPC will be installed. It is better to choose a folder outside of the add-ons directory. If you don't want to change anything for P3Dv4, then you can select to install in the old FSUIPC5 Modules folder (but I would recommend against this). All this (and more) explained in the Installation guide. Please read that document.

As I said, you have nothing in your FSUIPC6.ini - it is a default one created when none is found. If you want to preserve your settings from FSUIPC5 to FSUIPC6, you just need to copy your FSUIPC5.ini file to your FSUIPC6 installation directory (and also copy all other files you need, such as .lua and .mcro), and rename your FSUIPC5.ini to FSUIPC6.ini. Please see the provided Installation guide. This explains your options and how to migrate.

You have no settings in your ini. Did you rename your FSUIPC5.ini file to FSUIPC6.ini (and copy it to the correct location if changed)? Please see the provided Installation guide. (And there is no [Auto] section, so nothing is being started)

Hi Simone, what version of FSUIPC6 are you using? There were some issues in earlier versions of FSUIPC6 (relating to the use of 'require' and the [undocumented] LuaPath ini parameter), but these have been fixed. The latest version is 6.0.8, so if not using that please update first and try again. If you are still having issues, I need to see your .log and .ini files. John

Did you download and try the latest installer? If you got 'invalid Opcode' message, I presume not. Download the latest installer and try that. Before you do, run P3D once first (just start it and then exit). If that doesn't work, only then re-install the client. P3D installs 3 components: client, scenery and content. To uninstall the client, you need to go into the windows App and Features and uninstall from there, just as you would uninstall/remove any program. One removed, you re-install by running the Install_Client.msi provided by P3D (it will be in the folder where you extracted P3D after download). It will ask you if you want to deregister - click 'No'.

Are you sure? FSUIPC6 will only remove the folder if its empty after removing the files it has installed. It will not remove key and ini files, and so the folder will remain if its not empty. Maybe you can attach the created uninstall log. You shouldn't need to register again. If the installer finds a .key file in your installation directory, it will populate the fields in the registration dialog, but you don't have to register - just click 'Skip'. If the dialog isn't populated, it means that no key file was detected. In this case, you either have to register again, or you can skip and copy your key file across from its previous location.

For other users who have this problem (i.e. the installer is unable to determine the location of your P3D installation), it is recommended to: - re-install the P3D client and run P3D once. This should fix the registry entries, - download and run the latest FSUIPC installer - if this doesn't work, you could try this: https://www.nmgsimulations.co.za/flight-simulator-registry-fixer/

Glad it's now working.

Have you ran P3D since installation? If not, please do that before trying to install FSUIPC.

What version of the installer did you try (check first line in Details output)? For installer v1.2.2 this is what I expected. If you get that with v1.2.3, then there are no reg keys I can use to determine the location. Did you try re-installing the client?

Hi Dennis, this has already been reported: It seems this is on PMDG who are investigating. John

I know this. I am asking you to copy the text from the Details window and paste that for me to see (so I can see the whole text) rather than taking a screen-shot. However, this is now redundant as I know what the problem is.

I've just added a check for a second reg key if the first can't be found, in installer 1.2.3. Can you please download again and try that one.

I cannot access that link - can you not just attach it?

No problem - glad it's working for you.

I have corrected the problem in the installer. It will now show a message an exit if it cannot determine where either P3Dv4 or P3Dv5 is installed. However, this will not help you that much as you still won't be able to install FSUIPC6. I need to determine why you don't have the P3D registry keys installed. Could you try re-installing the P3D Client, then download and try the latest installer for FSUIPCv6.0.8 \9installer version 1.2.2) I am going to install the latest 4.5 HF to see if there is an issue there. Thanks, John

Pierluigi, thanks for the pictures, but what I really need is the log. Next time, if the log file isn't produced, can you copy the log text that is displayed when you click the 'Details' button, and paste that for me. But the picture of the small section of the log shows what you issue is: the installer can't determine where your P3D installation is from the registry (or if it is installed at all). I will look into handling this better - the installer should really have aborted (nicely!) and not installed anything, as it cannot find either P3Dv4 or P3Dv5 on your system. This is also why its defaulting to a P3Dv5 folder for your installation. What version of P3Dv4 to you have installed? I've not installed the latest v4.5 HF, maybe they've changed the registry keys used.

Sorry, but what has this got to do with FSUIPC? I think you posted in the wrong forum.

Did you do this manually? Installing/uninstalling FSUIPC will only ever removes files it creates during the installation process, as well as log files. It will not remove .ini or .key files (or any other files, such as .mcro or .lua) so that these can be re-used, and these must be manually removed if needed.

Maybe you could also try only installing the dll (i.e. uncheck the other sections - 'Documentation' and 'Extras'). I need to narrow it down to determine which install section is generating that error. If that works ok, you can then add the others back in, one at a time, to determine which install section is generating that error. Thanks, John

Can you press the 'Next' button, or is that inactive? If its active, please try that. The installation .log file will be in the same folder as the installer - it is only copied to the installation folder at the end of (successful) installation. Could you check to see if you have a .log file there and if so please show it to me. So you still get the pop-up 'Invalid opcode' message, but you can complete the installation? Do you have an installation log for this - if so, please post it. So FSUIPC is actually installed and running via this method? That message is most probably because the installer didn't complete and didn't write the reg keys expected by the uninstaller. It would also be helpful if you attached the full uninstall log, so I can check this. Do you have any anti-virus software running (besides Windows Defender)? If so, maybe also try with this de-activated. Thanks PierLuigi, John
