[supp]

I've tested the v.2.7.3 at windows 10/7 32/64 bit Systems. 4 times. Everythings running fine here.
anyway, please try to attach the logs when you need support.

Be sure vcredist is installed, since there were many that are having this issue cause its missing.

for those having the (like you call it) '0 kb bug'.

You can debug it by yourself:

1. Run Texture Tool and do all steps til' the file gets not created (0 kb)
2. open the TextureTool.log file and look for "running command:" (for example: Running command:TexturePacker -input C:\Users\me\Downloads\test -output C:\Users\me\Downloads\test\Textures.xbt)
3. copy the red marked command
4. open your %temp% directory. (C:\Users\YourName\AppData\Local\Temp\")
5. shift+ rightclick at some free space and click on "open commandline here"
6. paste the command and press enter

Texture Tool is running now manually. If there are any errors you will see them there, maybe you could also post the error for me that i can debug the issue.
Many thanks
