Omg hours of trying other methods and this is what worked. Wish I found this first! Thank you all I was missing was a certain version of visual c++ this did the trick

[uxmunzir]

Thank you very much. It worked. I have tried many methods. Then finally an idea occurred to me that I downloaded this repack from Doody's official websites and they must have a forum where they share the error they encounter with their viewers. So I searched and found this video. This is such a simple method.

Always a fan of your works DODI...
Just want to mention a few things,
It's always better to Uninstall every vcredist and reinstall the whole package,
Setup virtual memory in each drive of your computer depending on the free spaces, and for me I prefer to manually put the isdone.dll and unarc.dll into the sys32 and syswow64 folder and register them through CMD.
Last but not the least you have to disable the windows defender through following steps and not by just clicking the real time protection tab...
From task scheduler as well as group edit policy...
Only then it will be completely off....
Else random stuck problem will happen while installing the repacks...
Thanks DODI as always for your amazing works... ❤️❤️❤️

So guys i found a tricky fix for this error (at least works for me, and i'm gonna post this under various videos, yes i tried this with various games)

After triying all the possible solutions i started wondering if the setup was messing up some files at the start of the installation process, so after various attempts i discovered that when i start the setup some megabytes of data gets deleted randomly from the biggest files (data1 and data2 most of the times). I started re-checking the files with Deluge (qBittorrent was really weird to use for this fix, since it wasn't downloading missing files fastly after the re-check) and when the torrent reached 100% i ran the setup again : always the same problem.

What i did may sound strange but you have to run the setup and after the installation process started, you have to re-check files with Deluge (WHILE the installation is running and obviously before the error message) and make the download return to 100% again.

This fixed the problem for me (cannot guarantee the fix for you, sorry)


I hope I was helpful :)

Thanks for the video dodi, i got really frustrated turns out it was just the redist 😂

Let me add another important point regarding unarc dll error code 12.
Definitely it is caused by missing Microsoft visual studio library version.
And, it may not be solved just by downloading and installing the all in one packages...
Let me explain why...
1. First of all each of these repacks uses the %temp% directory to download the unarc.dll, isdone.dll and other relevant files. So, first of all, you have to change UAC to never notify, block the windows defender using defender blocker and changing registry key (mere disabling the AV will never be the solution)& give access rights to the setup executables from security and compatibility settings...
2. Now, Do install all the vcredist for both 86 and 64 versions.
3. You may still get the error. Why? Because before 2015 version of vc redist the older versions like 2012 or 2013 has this problem of not incorporating all the libraries from its previous versions...
Now, suppose a game is using a certain version of vc redist 2012 and u have installed the latest vc redist 2012, you will get the error still, because it may happen that a library used by the game was present in that older version of vcredist 2012 and not on the latest version of vc redist 2012.
4. Now what is the solution for that?
First of all clear the %temp%, temp and prefetch folders using win+r.
Then, start the installation as usual clicking the setup, after some time, when the error pops up, don't click ok, because that will roll back the changes and will delete the temp folders which is useful. Just end the task from task manager so that the temp folders preferably named as "IS-×××" or something like that is still there in the %temp% directory.
Now go to that folder, there you will find the exact vcredist version whose library is used while packing this game.
Install that version.
Now after a fresh restart, start the setup again but this time after unchecking the tick boxes of directx, and vcredists from the setup...
Run the setup with proper rights and it will be installed without showing the error code 12 for sure.
Note : DODI you are awesome as usual. Thought of adding this tip here. ❤️
Edit : If none of the above mentioned things works for you, the below technique will surely work.
Lower the no of Cpu cores.
Within MS Config > Boot Options > Advanced, you will get no of cpu cores to be used, lower it down to 4 or below,
Apply and restart, run the setup again, it will be installed for sure, majority of the new high core CPU is causing these problems now a days.
After installing, again change the cores and restart ur pc and enjoy. 😊

I tried so many ways still not work. Install c++ all in one pack, set virtual memory, try to install game in safe mode, using dll fixer to scan and fix files and errors, change my windows, chang folder or change name, run setup as administrator and chang compatibility to windows 7, verify all system files and fix it, turn off all option in windows defender and firewall, and so many way. I even get isdone.dll error code 1, code 12 and code 11 for fitgirl and codex setup. Don't know what to do please help me 😢
