OnBegin doesn't execute
Hi,
I"m using Installshield 12 demo version.
When I run my test project the OnBegin event doesn't execute.
Below is my source code in setup.rul
Any help will be much appreciated.
Thanks

Can you try running it in DEBUG mode and step thru' the code?

Hi Tampaite,
I tried running in debug mode but wasn't able to step through the code.
Does it matter that I am using an msi project instead of an installscript project?
I tried using an install script project and installscript\msi project and neither would run my code.
Does the demo version have that feature disabled?
Thanks

It shouldn't matter which project you create. Evaluation version doesn't have DEBUG disabled(I just downloaded a copy and verified it).
Can you just add the below simple messagebox and see if you can step into it?
MessageBox("Hello World", INFORMATION);

InstallScript events (such as OnBegin) are supported only by InstallScript and InstallScript MSI projects. To run InstallScript code in a Basic MSI project, an InstallScript custom action needs to be created and sequenced where/when you would like the code to run. In addition, the custom action function needs to be defined and exported in the setup.rul (see the MyFunction prototype and implementation in the original post).
If you would like to use an event driven script, an InstallScript project is the recommended project type.

One other thing to note, and this may not matter if the code the post has in OnBegin is just some test code, but the GetDisk function is used to return the drive portion of a path passed to it. For example, GetDisk will return 'C:' if the path 'C:\Program Files\Test' was passed (the function return value is successful if a drive could be parsed out of the path, failure otherwise). To determine if a drive is present on a machine, use the ExistsDisk function instead which returns EXISTS (0) if the drive is present and NOTEXISTS (-1) if it isn't.
