I am using the latest version of UPX packer.
I am on win10, latest version adn I pack an x64 file.
I managed to pack other files in the past with no running issues.

I packed now an exe file and when I try to run it I get this error:
"The application was unable to start correctly 0xc0000142"

I made sure of the following:

• The non packed exe can run on it's own

• When I unpack it using: upx -d <packed file> and try to run it, it runs as expected.

• I tried various compression levels and various uxp version and compression methods

  What can i do about it?.

Problems like that happened many times in the past. The best you can do is to file an issue via official UPX GitHub repo. Eventually, you can try using some older version of UPX.
