I have custom actions that runs some exes where I check the exit code.
If the exit code is wrong (1 I think) the installer displays a message box informing the user that the current action finished with exit code 1.
How can I change the text displayed in the message box?
I'm using InstallShield
Thanks

Ah, the joys of return values...One day, MS will standardise on return values. Quite why it decided that most functions should return 0 as success but others a non-zero value has always alluded me. Then to compound the confusion by using '1' as the success value for CAs in Windows Installer....it defies belief, it really does. Anyway....

You can't, it's built in to the Windows Installer engine. Better to handle the error 'internally' to your CA and present your own dialog/MsgBox there (you can use the IE object to present dialogs as an alternative to MsgBox). If the return value of the CA determines some future action/inaction, set a Windows Installer property (or registry entry) accordingly.

Most, if not all, messages generated by the Windows Installer are listed in the Error table and UIText table.

Really? Create a guaranteed-to-fail CA (e.g. run a non-existent EXE or an EXE with an invalid argument) and see if a single sentence from either of those tables appears in the resulting dialog. Certainly some of the *common* errors appear in the Errors table (1603 and so on) and one can add the missing ones if desired.
@cornel_gav, What I think you're saying is that the *EXE* returns a non-zero value. As I mentioned, a return value of 1 from a *CA* indicates success, not failure. MS guidelines state that EXEs return zero as a success failure and anything else indicates a failure. Did you author the CA? I suspect this is a vendor MSI calling perhaps a DLL function, in which case, you're stumped and you'd be better off trying to determine why the call is failing.
