Let me add an example here      I m trying to build Alluxio on windows platform and got the same issue  it s because the pom xml contains below step            lt plugin gt           lt artifactId gt exec-maven-plugin lt  artifactId gt           lt groupId gt org codehaus mojo lt  groupId gt           lt inherited gt false lt  inherited gt           lt executions gt             lt execution gt               lt id gt Check that there are no Windows line endings lt  id gt               lt phase gt compile lt  phase gt               lt goals gt                 lt goal gt exec lt  goal gt               lt  goals gt               lt configuration gt                 lt executable gt   build path  style check no windows line endings sh lt  executable gt               lt  configuration gt             lt  execution gt           lt  executions gt         lt  plugin gt    The  sh file is not executable on windows so the error throws    Comment it out if you do want build Alluxio on windows

If you are Clion anyOtherJetBrainsIDE user  and yourFile exe cause this problem  just delete it and let the app create and link it with libs from a scratch  It helps

The most likely explanations for that error are    The file you are attempting to load is not an executable file  CreateProcess requires you to provide an executable file  If you wish to be able to open any file with its associated application then you need ShellExecute rather than CreateProcess  There is a problem loading one of the dependencies of the executable  i e  the DLLs that are linked to the executable  The most common reason for that is a mismatch between a 32 bit executable and a 64 bit DLL  or vice versa  To investigate  use Dependency Walker s profile mode to check exactly what is going wrong    Reading down to the bottom of the code  I can see that the problem is number 1

Your Button2Click and Button3Click functions pass klad xls and smimime txt  These files most likely aren t actual executables indeed   In order to open arbitrary files using the application associated with them  use ShellExecute
