custom action, needs to change path in parameters ?

[amapic]

Hi,

I would like to execute the .bat file which contains the code below in a custom action:

lanceetcache.exe buttonevent_cs.exe -v
exit

=> "buttonevent_cs.exe" is a parameter of the first exe. 

First, this .bat, lanceetcache.exe and buttonevent_cs.exe are in the same folder (which is [INSTALLDIR] once installed)

Second, The execution of the .bat works when we execute it locally.  It does'nt work when I call this .bat in a custom action during installation. Do i have to I have the adapt the "buttonevent_cs.exe " parameter by something like " [INSTALLDIR]buttonevent_cs.exe"  ?

Thank you
