I am trying to Run an exe using Custom Actions I have copied my exe file + the files it refers to in it's root directory while running, in the Common Files Folder
But on Installing It gives the following error -
"Error 1721.There is a problem with this Windows Installer package.A program required for this install to complete could not be run. Contact your support personnel or package vendor"
But when I am using some standalone exe file like "Notepad.exe" It works perfectly fine..
There is no problem in my exe file and it runs perfectly fine when I manually do it by double clicking it.
You'll probably find that the executable has been written badly (apologies if it was you :rolleyes:) Coding best practice is that when an application exits successfully it should return an exit code of 0. You obviously know how to run an exe custom action if you got notepad to launch ok. You will probably find that your custom action is authored ok and your custom action is running ok too but because the application is returning something other than 0 for a success then installer presumes an error has happened. To get around this all you can really do (short of asking for a rewrite of the code if possible) is change your custom action from Synchronous (check exit code) to Synchronous (ignores exit code). The problem to be aware of with this though is that if it really does fail, your installation will continue on blindly. If you have some reg key or file to test afterwards to check it ran ok then you might want to consider doing that too.
Oh and ps. If you exe makes changes to your machine its good practice to run it in deferred mode, you have yours set to immediate.
If you're trying to run an executable being delivered by your installer, you need to run as a deferred execution. Immediate runs as soon as the installer is read in, but before any files are copied.
