I have an exe on many machines, running NT/2000/XP, that have only needed the LVruntime engine to work properly. On one new XP computer, even with LVRT there, the support files in the data folder are not recognized.
Yes, I do have an installer. The installation may have been corrupted because we reinstalled and that machine works properly now. However, something even wierder, on XP a machine that had been working suddenly couldn't find MSVCRTD.DLL. I have had these problems only on XP.
