Ill download a copy of 4.5, as the latest version I have currently 4.22 . Does it matter what compression level you use?

ciper,

Have any feeling why upx would be able to compress v4.22 of kix32.exe, but using the exact same commandline, be unable to compress v4.50 of kix32.exe ? Have you seen behavior like this before ?
