Exe cannot find top-level vi

[pincpanter]

I have a problem on some (not all) systems featuring XP lite - a customizable, small footprint version of XP.

Say I install an application A through an installer including the LV runtime (7.0). After that, I copy on the system an executable file B.exe; if I try to run B, the LabView splash screen shows up for a while, then the runtime opens the "Choose vi to load" dialog. I'm forced to generate and run an installation of B in order to have the possibility to execute it.

A similar problem appears if I update the original application by simply copying a newer version of the A.exe file. Again, I need to uninstall and reinstall application A.

Have you already seen something similar or do you have any explanation for this behaviour?

Thanks in advance for any contribution.

Hi Paolo,

usually you can replace the exe without any need to re-install the full setup (including LV runtime).

Usually you can also run a second exe without installing the runtime twice (which will not happen) as long as you don't need any additional libs/packages... (True for same LV version.)

So maybe this behaviour is due to XPlite?

Hi GerdW, thank you for your answer.

Yes, the culprit is most probably the operating system. I didn't prepare it myself, so I don't have at hand the list of the removed features.

I was just wondering if the problem can be traced to a known issue using the vast collective experience of the forumers. This would give me a hint about a possible workaround.
