I use TMS Component Pack I have a program using AdvDropDown. It compiles with 32 Bit.
But not with 64Bits, because it tells me that  ATXPVS has the wrong format (32Bit).

I cannot find ATXPVS.pas. Where is it or what is it?

Sincerely Peter

Is the folder where ATXPVS.pas is located added to your 64bit library path?
