Hello Vampchild, 

This problem is most often on the browser and the security settings you are using when trying to download the Texture Transformer files. Google Chrome is fairly well known for doing that. You can temporarily removing or change the security settings, or you can simply re-name the downloaded files to something like TextTrans_1.zip, TextTrans_2.zip, etc if the files are on your computer. Renaming saves you from having to download again, because usually the browser still downloads the file, it just names them so your computer won't know how to open them.

Please note the security settings for your browser, windows, and any anti-virus software can cause these types of issues. I can assure you our Blacksmith3D and Texture Transformer files are safe. However, if you are uncomfortable temporarily changing or removing those settings in order to properly download and/or install our products, I will gladly issue you a refund.

 Best Regards,

Blacksmith3D
