If you mean upgrading to Windows 10, I have been using the Mod Tools without any issues in Windows 10.
There is no way to know what is causing your error without more information. At this point, the only remaining option is to put your mod folder in a ZIP and PM me a link to download it.
I upgraded with a newer Graphics Card, and Hard Drive. During the back up process, it said that some files had names too long (over 400 files, had no time to go through them.) and won't be copied over. Copying the backup to the new HD had the same thing. That would mean that a lot of data was not copied over.
Right, I tried building the mod again just to generate the error to copy this here -

I hope this can help.
Please let me know exactly what kind of information I should provide you. I would like to share all the necessary information you are looking for before I send you my mod.
And I'm using Windows 7.
