execwait doesn't wait in Vista

I am using execwait to launch a batch file that copies some files from a network location and then runs a setup program.
XP works fine, but under Vista the nsis installer just continues after a couple of seconds while the files are still being copied in the DOS window?

I was also experiencing the similar problem with nsExec::

You can use CopyFiles to copy files.

As for not waiting - you should execute and wait for cmd.exe, or better yet - %COMSPEC%, as .bat files are not really executables.

Thanks for the quick reply.

I have just tested the comspec method

ReadEnvStr $3 COMSPEC
ExecWait '"$3" /K r:\latest\installcam.cmd'

Again, this works fine on XP, but still continues after a few seconds in Vista whilst the command window is still open?

Any suggestions?

/K means keep open after the batch is done, try /C and see if maybe your batch file has a bug

Try throwing Vista out the window. That might help.

Frustration based humor aside, my best suggestion is that you don't use a batch file and use CopyFiles. If you really must use a batch file, give me something to test this on so I can reproduce and check it with my own eyes.
