Re: [Py2exe-users] link checksum and avast

[Gufflet Y. <yve...@or...>]

Thanks Dan and Mark for your answers.
It appears you do not tell the same thing.
Mark, did you answer on the basis of the forum link I sent, or do you 
know the heart of py2exe ?
Dan did you check the checksum with depends.exe or did you assume you 
had no problem with checksum ?

Could you check for your executables what it indicates with depends.exe ?

http://www.dependencywalker.com/

Effectively, I am deploying without python installed and I had a lot of 
problem to incorporate with a manifest the versions 9.0.21022.8 of 
msvcr90.dll (and co). And I thought it was the problem. I used by error 
32 bits version and then 64 bits version. Still do not work and then I 
saw it was conflicting with AV. I cannot assume that the person do not 
use AV or that an antivirus will not block because of an invalid link 
checksum.

Have you got any idea of a minimal configuration for the build that do 
not generate this link checksum ?

Do you think it is because the dll used at compilation or at runtime are 
not the same and that I am still having problem with dll hell or winsws 
hell ?

Any suggestions ?
