Discrepancy between launcher version and game version hoiv [SOLVED]

[Rydelta]

Hello, I hope someone can help.

My friend and I are trying to play on the latest patch and in the launcher both of our games indicate patch 1.6.1 (55d5) however in game his changes to 1.6.1 (c9e6) which is weird because neither of us have mods installed.

We did the usual trouble shooting of reinstalling and deleting all local files and documents. But to no avail. We went back a patch but the same problem occured (only with different version numbers).

Again i hope someone here has run into this problem before and knows the solution.

The in-game checksum is the only one you should care about, do not pay attention to the one in the launcher.

The current live version is 1.6.1 with the checksum 55d5

You need to have the same version AND the same checksum in order to play in the same multiplayer game. Keep in mind that most mods will change the checksum. Also note that DLC's have no impact on checksums.

You can first try the 'Clear user directory' button on the launcher and see if that helps.

If not then you will need to do a clean re-install. A clean re-install will fix all checksum issues but is a little more hassle:

We tried the above sadly it did not resolve our issue

A properly done clean re-install fixes all checksum issues.

Why? Because if you do it properly then there is no trace left of the game after the uninstall part to mess with the new installation. So make sure you both followed the instruction exactly.

Hello there, I have a potential solution for you,

Me and a friend had a similar issue with a wrong checksum (mine was 55d5 and my friend had c9e6)

we tried many things from uninstalling the game, to deleting the files and folders in the C:\Users\UserName\Documents\Paradox Interactive\Hearts of Iron IV folder, none of it worked.

Only just now we managed to solve the issue by doing a number of things but chiefly my friend deleted the Steam Workshop folder found in C:\Program Files (x86)\Steam\steamapps\workshop as well as uninstalling the game and manually deleting the files and folders in the C:\Users\UserName\Documents\Paradox Interactive\Hearts of Iron IV folder.

Despite the mods being inactive they were still influencing the game somehow and reinstalling the game alone didn't change the fact his checksum was different.

Give this a try, hope it helps.

@Gunner11, as I mentioned above, a properly done clean re-install fixes all checksum issues. Just follow the instructions I linked to exactly and in the exact order.
