i had to add manually in exe.dll located in %programdata% this command i dont know what to do
You DO NOT have to manually add the modules to the XML file and, in fact, you SHOULD NOT, because we don't use the centralized XML method anymore, but the more proper native way of the add-on.xml, which is private for each product.
If you add the module to the EXE.XML, the module would be loaded TWICE, causing all sort of issues. The installer, of course, correctly adds everything that needs to be added so, you should not make any changes manually.
However, it's possible (under certain versions of the sim), that an already corrupted .XML file (either because you have edited it by hand or because of a defective installer of another product that DO use that file), could prevent modules loaded through the add-on.xml method from loading so, that's why maybe you *though* you had to add the module manually, but you don't. The solution in this case would be just removing the XML files, which we don't use.
Or, the program might have simply being blocked by the antivirus, because of a bug of the antivirus. The solution in this case is to reinstall with the antivirus disabled and configure it to exclude the whole Addon Manager from scanning.
