No, there's definitely no problem with the signing tool. I sign my software since the last 3 years, on a daily basis.
But I will try again and will play with settings and let you know my result.

So, you are 100% sure I can sign the protected (and boxed) application without any issue?
I dont want to purchase it just to figure out that I cannot sign it.

Various tools, so for example x2net signcode. I can sign any program with it, be it compressed, encrypted, whatever, just not when the progeam is "boxed". It will just crash when trying to sign the boxed application.

The problem is, the tools used to sign the executable are crashing when trying to sign a boxed executable.

I tried to digitally sign the boxed executable, but it failed. Signing the unboxed executable is no issue, but signing a boxed exe wont work.

How can I digitally sign a protected exe, without causing the protexted exe to "think" it was modified?
