Olivier,
What version of LabVIEW are you using to build your application? On a remote computer you should only need the drivers you are using and the Run-Time Engine. You can attach installers to LabVIEW 8 installers, but for previous versions you will have to add it by opening the installer configuration page, configuring your installer and then configure the Advanced properties. This will allow you to attach a EXE to the installer which you can run. Also depending on the version of LabVIEW will affect the OS version that you will be able to install the RTE on. LabVIEW 7.0 is the last version that can be installed on Windows 98.
Please let me know if you have any further questions and please include the version of LabVIEW you are using. Thanks!
Andy F.
