Program does not run on Windows 64 bits (AWS) lazarus / 34-Windows ---------------------------------------------------------------------- Almir.Bispo · 2020-08-05 18:12 Hello People! I had a project compiled in Windows 7 (32 bits).It's run perfectly on XP,7,8,server 2012,server 2003. But can not to run it on Amazon Web Server (Amd 64bits) .I had used the same code to compile  (using LAZARUS on Windows 64bits). The link bellow is a exemple than i made with Windows 32 bits but the same application does not run on Windows 64 bits https://www.quora.com/How-do-I-write-Pascal-programs-on-the- web/answer/Almir-Bispo The code compile perfectly in any Windows.The application crash only in Windows 64bits ---------------------------------------------------------------------- ASBzone · 2020-08-05 21:00 Quote from: Almir.Bispo on August 05, 2020, 08:12:10 pmThe code compile perfectly in any Windows.The application crash only in Windows 64bits Are you running 64-bit Apache in AWS?  Without a code sample that can be compiled, it will be harder to troubleshoot this app than one where you provide some code. ---------------------------------------------------------------------- Almir.Bispo · 2020-08-05 23:59 Quote from: ASBzone on August 05, 2020, 11:00:20 pmQuote from: Almir.Bispo on August 05, 2020, 08:12:10 pmThe code compile perfectly in any Windows.The application crash only in Windows 64bits Are you running 64-bit Apache in AWS?  Without a code sample that can be compiled, it will be harder to troubleshoot this app than one where you provide some code.

I don't think I noticed the answer to the above question.
