Hi Syam, I think I found the potential issue. I kind of add the file one by one and found the crash will happen once I replace the data01.rda. I think this file might control some initiation from Anno1404Addon.exe. I also check some installation tutorials on Youtube and found that not sure why my game version is old one v4.00.4253 / 1.4514.940870 . Already asked a customer support for it. However, just want to say thanks to you. Great mod and can't wait to build the Venetian buildings!
