Problem with execute on Win7 Enterprise
Hello,

I've created a Java launcher with NSIS, the generated exe is called "dbupdate.exe".
I've created an installer with NSIS, which execute the launcher.

It runs very fine (since years) on Win2000, XP, Vista (all Variants) and Win7 Home.

But now, tested on Win7 Enterprise, the launcher doesn't start. There's no message and the execute returns error 0. Simply the launcher doesn't start.

The code:
ExecWait '"$INSTDIR\dbupdate.exe" $0' $1
IntCmp $1 0 ExecOK +1 +1
!insertmacro ShowError 31
ExecOK:
....

The installer needs admin rights ("RequestExecutionLevel highest"), the launcher needs only user rights. I've tried several combinations of requsted rights and exec-variants (exec, execwait, execshell, nsExec::ExecToStack, ...) but the result is all the same.

At another place in code, I execute another external programm ("unzip.exe"). This execution runs without problems on every OS variant.

What's wrong?

Thank you very much for your help in advance!
Viktor
