- Disable AV
- Try to run as admin
- Make sure to have enough free RAM
- Run setup.exe from a short folder path and install to a short folder path

If no one post the same problem i must assume that you are the only person who have problems with this.
Otherwise go with just srep+lzma

PS: I've used srep x64 for this, report back if this problem persists without pzlib to ensure pzlib is not the problem. Will share a setup with srep x86 then. I mean, 8GB RAM is not that much today...
