How can i send my test file to you?

@LakerMoon, I am not sure whether there is still a problem here.. If there is a problem, you can share a link to the program in subject and I'll try to debug this. If there is no problem, kindly close this issue.

my program: [ testPE32upx.exe ] Link：https://cowtransfer.com/s/ee1ceef40dbf46

It looks like the packed binary does run, even though it fails afterwards - probably for another reason: Please checkout dev branch and see if it works for you; it will take about a minute for the binary to unpack.

I use master branch, it fails before unpack. Do you use dev branch?

I use dev branch to have a try.

I use dev branch and run packed binary. It doesn't work and exitprocess before it run oep.

Close for now.

We updated the codebase for Qiling and Unicorn since this issue being posted.

Feel free to try the latest version.
