EzBatchAddPath Example

InstallShield 2016 » InstallScript Language Reference

Note • To call this function in a Basic MSI setup, you must first create a custom action for the entry-point function, execute the custom action in a sequence or as the result of a dialog's control event, and then build the release.

/*--------------------------------------------------------------*\

*

* InstallShield Example Script

*

* Demonstrates the EzBatchAddPath function.

*

* First, BatchSetFileName is called to change the default batch

* file to EXAMPLE_BATCH. Then EzBatchAddPath is then called to

* add C:\WINDOWS to the beginning of the PATH statement.  A

* second call to EzBatchAddPath adds C:\UTILS after the WINDOWS

* keyword in the PATH statement.

*

* Note: Before running this script, create a batch file

*       named ISExampl.bat and store it in the root of

*       drive C.
