Hi, I'm learning the base of modding, following exactly the STEP 2.2.9.1 recommandations. Everything was ok until i had to apply BCF with WB. Launching Wrye bash from MO make the "installer" tab getting errors. I re-installed WB three times with the recommended settings. Finally, i red it's normal since MO doesn't support WB installer any more. So, i run WB from directly from it's executable: in this version, i dont see my MO mods in the mod tab. I have one archive Bain & Wizard and two archives: I follow the instructions (Exctract Wizard archive in folder Bain Converters; Put the two archives in Bain installer folder; Select one of the two archives>conversions>apply>ExtractedBain&WizardArchive.7z) I keep the name proposed by WB. During the work process, i get a wyPython window which says: I red the BCF threads but it didn't help me. Probably did i something wrong, may be need i this kind of product for windows: https://windowstechies.com/-/en/filename/?t=60&k=assertion%20failed%20c%2B%2B&m=b&u=&c=89349541289&file=assertion%20failed%20c%2B%2B Thanks a lot for your help.
