Summary

InstallScript MSI installer packages created with InstallShield 2018 SP1, fail to launch when located directly on a root folder

Symptoms

When creating an InstallScript MSI release using the Traditional Style on InstallShield 2018 SP1, and then launching the installer from a root directory (e.g. C:\setup.exe), the installer will begin to launch but immediately exit. Running the installer with /debuglog parameter will show the following error in the InstallShield.log:

Launch result 1, exit code -1073741819

The issue will also occur if launching from the root directory on a CD, DVD, ISO, USB flash drive, or any other storage device. Launching the installer from a subfolder in the root directory does not reproduce the issue (e.g. C:\subfolder\setup.exe). This issue also does not reproduce on InstallShield 2018 (without SP1) and prior.

Cause

This problem has been reproduced and determined to be an issue in our software.

Steps To Reproduce

1. Create a new Installscript MSI project
2. Keep the InstallScript User Interface Type setting to Traditional Style
3. Build a Setup.exe installer
4. Move the Setup.exe to any root directory such as C:\
5. Attempt to launch the Setup.exe
