Minimal VISA 4.1 serial runtime installer?

[Klaus_M]

Is it possible to generate a minimal sized installer for VISA4.1 serial (RS-323) in LabVIEW 8.2?
The target environment is LabVIEW8.2.1 runtime and an application that needs only serial support and a resource list.

1. Our customers do not understand, why they have to install all NI-VISA drivers or select items during installation, that they are not sure about.

2. Customers are also afraid, that already existing, earlier LabVIEW installations may get corrupted.

The most convenient solution would be to include some DLLs into the application installer. So our users cannot make errors.
(Like it was in the good old LabVIEW 6.x times ;-)) Is this possible?

Thanks in advance.

The essential part of NI-VISA is not simply VISA32.DLL. It is a bigger system software tons of runtime DLL, Windows Services, Registry, and more. 

NI provides "runtime-engine" version of NI-VISA, which is much smaller than "full" development version.  As for NI-VISA 4.1, the SETUP image of full version is over 200MB but runtime-engine version is only 28MB.  The only solution is use this.
