"unfinished" installation prevents me from installing further mods

[clueless moduser]

Hello, everyone, I need some help here:

I just downloaded some bg2 mods for my new game, but when I try to install them, the setup claims, that I should first complete the setup of another mod I installed (which I did install completely and which works normally) - but I also get that message when I run the setup of that very mod and the mod's .bat file gives me an error...  

So, my question is: Is there a way to clear the troublesome mod off the 'installation schedule', or is there a way to start all over with my mod installations that doesn't require running the mod setup files (except the tiresome process of reinstalling the whole game)?  Or will I have to give you the detailed version of the story to  find a specific solution?
Thanks in advance.

Yes, please, delete weidu.lock from your BG2 directory and run Setup-somemod.exe again. In the end, press Enter to finish the installation. It was an issue specific to v200; it is no longer present in the latest version.
