ExecWait crashes on Vista

[simulation]

Hi Guys,

I'm looking for some advice on traking a crash problem on Vista only.

Section4
ExecWait '"t:\batch\cgdcompile-02.cmd"'
SectionEnd

My installer has 5 sections and it crashes consistantly on the 4th section when I run all the sections. If just run the forth section it runs fine.

All I can think is that something I am doing in an earlier section is having an adverse effect on the Exec command. These is over 1000 lines in the script, so I am relucant to post it and I'm sure you won't want to read that lot

When execwait is run the installer crashes and a CMD.EXE (without a window)is left as a process?

I have tried exec, execwait, nsExec::ExecToLog etc.


I can only think that XP is handling any memory issues better than Vista? Does anyone have any ideas as what could cause this situation or what I should be looking for?

Any tips greatfully recieved.

Thanks
