Errors Installing/Uninstalling Mods

[BelacRLJ]

I am running Windows 10 and have Baldur's Gate I only, through Steam.  

I tried to install the current versions of Sword Coast Stratagems and the BG1 NPC Project, and for both got the following error:

FATAL ERROR: Sys_error(".\\lang\\en_us\\dialog.tlk: Permission denied")

When I opened a game file, dialogue options were screwed up and all choices were "Invalid(#####)".

Is there something I can do to get the mods to install correctly?

Well, first of all, is this a BG2 or BG1 game, you need to first run the game before you install mods to choose a language in game... and specifically if it's a BG1 + SoD, you need the modmerger(yes the blue text is a link to its beamdog forum thread). And here's the github page.

@BelacRLJ You need to move you default Steam Library outside of the C:\Program Files, that's my first guess.

@Jarno Mikkola Please forget about modmerge, don't suggest it. Instead, tell about DLCMerger since it doesn't give false-positive when the game files are 'verified' by Steam.

It’s BG1, without SoD.  I had run the game and chosen languages prior to installing mods.

 Should I try using modmerger anyway?  The error message arose after installing the first mod and after uninstalling each, so I’m also not sure it’s responsible for the corrupted dialogue options.

If it's without SoD, you don't need to install modmerge DLCMerger, follow second advise, move games outside of the C:\Program Files\ (and make sure game isn't run when you install mods)

Specifically, you need to make sure that you own the folder you install the game into, in a modern Windows 10 for example, this is here:

C:\Users\<user profile>\Games - or any other subfolder\BG1EE\ -for example, where the <user profile> is the username you use to log into the computer, as that's the only folders your computer recognizes as your "own" in the C -drive.

On updated Windows 7, the structure is same, but usually people also add in the Documents folder for ease of use, so you end up with:

C:\Users\<user profile>\Documents\Games\BG1EE\ ...

@AL|EN, I'll try... in the future. I don't use Steam, so..

I tried that and it worked for those, but I'm getting the same error trying to install the mini quests mod.  The install folder is now one under my user profile.
