I have been trying to install the Pico 8 on my new laptop wanting to move it from my old computer in which I have already installed it on just fine. I tried downloading it and went through the installation process, but when it finally done, it essentially put an empty program on my computer not even having a file size on the control panel only having the uninstaller work. I tried reinstalling it through administrator mode but the same issue occurred. As a last attempt, I tried downloading the zip file only to occur with the same issue having it delete itself off my computer.

Edit

I have no clue how I fixed it, but it seems to be working well!

What OS is it?

If you download the zip file and look at it with an unzip tool, do you see file sizes that seem right?

Do you use an Antivirus App? Some of them tend to block and delete "suspicious" Files right away without even asking or showing a Message; even Windows Defender (Default on Windows) is annoying me everytime I download Pico8...
