📋 About This Mod
This is the best functioning Wrye Mash that exists imo. This newer version of Wrye Mash Stand Alone (WMSA) Version 0. 0. 3 was released by Melchor and he has no objection to upload WMSA elsewhere. This version fixes the "cannot edit the file header" bug and other bugs that exist in Yacoby's version.
You don't have to mess anymore with Python nor WX, all is bundled in the executable. It is an automatic installer and I wrote step by step instructions below.
This version (0. 0. 3) should correct the problems that can be encountered on non US machines.
This WMSA is superior since it doesn't have the "cannot edit the file header" bug that exist in Yacoby's WMSA.
On the download page there is a question mark near the mod name. It says that some of the Nexusmods virus scanners reported the file as a virus. The staff believes it is a false positive. It is obviously a false positive however I provided an alternate download source from over at Great House Fliggerty. That is where I got the darn thing from in the first place. I will also provide a second mirror, you know, just for kicks :D Just click on the Mirror tab.
