EjectPack Installer V3.exe is the converted version of EjectPack Installer V3.bat i used Bat To Exe Converter by Fatih Kodak.
I just scanned EjectPack Installer V3.exe with VirusTotal and its detected by about 15 av's :( so if you want to use my pack but dont trust me just download it and install it manually: https://download.mc-packs.net/pack/4f4aaced624a607286b3bcd206ecb99c6398196b.zip
If you want to use my texture pack and trust me and the dev of Bat To Exe Converter just download and run EjectPack Installer V3.exe.
If you want to make your own get the batch code and edit it for your needs (url, txt name, texture pack name). Use an Filehoster like 000webhost to host a textfile containing the link to the texture pack hoster for example mc-packs.net.
