Okay I've spent a lot of time trying to figure out my following wix problem but I've yet to find an solution that works. The original goal was to run a bat file that had already been written right at the welcome screen that would do a hardware requirements pre-check at the beginning of the install and exit with an appropriate error dialog box if the conditions were not met without installing anything. At this point of the install you are unable to run a bat file because the files haven't been transferred to the local disk yet. So I figured I'd convert the batch file into an exe file and store it in the binary table and create a custom action of type 2. So when the user clicks on the next button from the welcome screen the exe is called from the binary table and executed. I managed to do this and everything looked great but there was no way to get the exit code from the exe so I couldn't spawn an error dialog if the hardware check failed. Wix only passes back a failed bat file if it's unable to properly execute it. So I figured I could write a C++ dll wrapper that would allow me to run the exe and then set an msi property based upon the exit code of the exe. Setting the property was no issue however I'm unable to get the location of the exe file that's stored in the binary table to the dll so that it can execute the executable. Essentially I can't find the executable (or have a link to it) that enables me to run it from the dll. Is there a solution to this issue or the first issue of dealing with exit codes from a exe. I haven't been able to find a solution to either of these two items and I've spent a fair bit of time working on this. I need help. ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by:
