Software Deployment

I take it your Win 7 build is 32-bit? If not, your program files folder will be named slightly differently. If so, ensure that your CA is running as Deferred in a System Context. Probably somewhere between InstallFiles and InstallFinalize. Then consider using a slightly different approach to hard coding the path to register.exe - perhaps a different type of custom action such as a VBScript using an environment variable to get the 'Program Files' folder? Or if 'register.exe' is installed with the package, use a 'Execute Program from Installed Files' custom action instead....

Thanks Captain_planet, my Win7 is 64bit, I have ran into an other situation , the package which I have created is working only on that XP machine not on any other XP machines, as I mentioned in my earlier post about the custom action, I have left the Property as default i.e., wisedebug mode, should I need to change this to something else moreover am using this CA in user sequence , Am I doing it right?

Please suggest,

Thanks.

first captain_planet already told you what to do, i suggest you reread his answer. why ask the question if you don't even bother to read the answers given to you.

your path should be using a folder reference as opposed to a path from a property.

[$componentKey]register.exe or similar.

you also need to run the exe as deferred in system context. you may also find uac is blocking your attempts at running elevated "if" that is the case you can use elevate.exe to get around it. but it shouldn't be an issue in this situation.
