Thanks for the help and ideas you two
@Cerez @Modder01 ! I don't necessarily care for the german localisation as i prefer to play it in english anyway and altough 5 bucks are not much i thought to myself there's gotta be a way to get this "1.40 magazine" version updated and patched to the latest one - and I actually got it working!
This is a long one:
I downloaded the official patch 1.50 and couldn't install it, as i described above, since all you get is a message "Age of Pirates - Caribbean Tales is not installed" which is utter bull**** of course, but it checks for version 1.41, and I suspect that the magazine version (Computerbild Spiele) is missing that version flag or something.
So i though to myself "what would this patch actually do to the install folder? Probably just replace some files in the install folder with newer ones". I tried unpacking the .exe with 7zip and some other unpackers, but no luck. I tried various method i found online, with unpacking in windows terminal, weird batch-file tricks and some messing around in the temps folder, all with no luck. I then found a program called "Universal Extractor 1.61". With this i was able to unpack the Patch 1.50 into its components. It had a folder called {app} which included a very similar file hierarchy as the install folder, with "engine.exe", "program" folder and "resource" and so on. Also "protect.dll" and "protect.exe" - yes, starforce. We'll come to that later though. First I copied over all content of the {app} folder into my AoP Install-folder and clicked replace, when prompted. I didn't want starforce to infest my system so i was very careful going on from here. Just starting the engine.exe started a starforce install which i could stop by clicking "no". OK. next i deleted "protect.dll and .exe from the folder and s´double clicked engine.exe - "starforce is missing from this system" was the rompt i was greeted with. OK. Here's where I downloaded a certain "no-DVD" including engine.exe, program/quests/quests_reaction.c, and some /modules/.dlls from a site I won't name here since i believe i'ts not allowed. I copied all of these into the Install-folder and at least the game did start now! But weird things kept happening, for example i had weird micro-stuttering the whole time while playing and these became worse. 5 crashes in 5 hours later, and i though i should investigate. I found out that immediately when starting the game, my cpu got loaded up to 98!!! %. I have a 12-core, 24 Thread system! Something was not right here! I replaced the engine.exe with the engine.exe from the Historical Immersion Supermod v.04 AAAAAAND everything worked perfectly now!
Afterwards I could install all of Cerez' Mods without any problems. I now run the updated version 1.5 vanilla, Supermod v5.0 Standalone, Supermod v4.0, and version 1.5 with Cerez' patches all in individual folders in my "Games" folder and can play each version when desired. phew.
So finally this is a working way to update the game-magazine-version (Computerbild Spiele) of AoP-CT to version 1.50, which was thought "un-updateable" on all german foums i searched on. I think i'd like to make an english/german tutorial thread for this so others don't need to figure this out but I have aquestion and I need your help here: When I, instead of using the no-DVD files, use the similar named modules/xxxxx.dlls (Location.dll, sea.dll, Soundservice.dll, Xinterface.dll) and the /program/quests/quest_reactions.c from the HI Supermod v.4, I get a "visual C++ runtime error" when starting the game. So i have to use the .exe from the HI-mod but the files from the no-dvd patch (modules/xxxxx.dlls (Location.dll, sea.dll, Soundservice.dll, Xinterface.dll) and the /program/quests/quest_reactions.c). I guess i will have to find another way for me to be able to provide a small v. 1.50 patch archive for the game magazine version, right? Or would you think it is ok to combine the unpacked 1.50 patch, these files from the no-dvd-archive and the HI-Supermod engine.exe into a special 1.4x to 1.5 patch?
It would be reat to provide this for all my fellow players from germany who can not use their game-magazine-version with a lot of the mods due to not being able to update.
Sorry for this huge post and all my questions.
Best.
