ExecWait with .msi file

Hello

ExecWait only works with an exe file?

ExecWait '"$INSTDIR\someprogram.exe"' works fine but ExecWait '"$INSTDIR\someprogram.msi"' doesnt work
Why?

TIA

If its more easy to you write this stupid answer against help me, thanks a lot

.msi files are not executables, they are essentially a file type and association to msiexec.exe - calling it that way won't work.

A better way to do it is to call it like this (VisualC 8 runtime in this case):

ExecWait 'msiexec /i "$INSTDIR\\vcredist.msi" /passive' $0 

If you want to know more options for msiexec, do a Start... Run... "msiexec.exe /?"

Thanks a lot CrushBug, this works fine to me
Thanks for your time
