I use the 8.2.1 application build along with the 8.2.1 Labview.The application is Labview and works fine. The files are for a Programming Tool done in Visual Basic.Comdlg32.ocxCwui.ocxMSCOMCTL.ocxRightx32.ocx Riched32.dllThese get installed in the system32 folder, that works, but the Tool can’t access them till they are (regsvr32) this has happened several times on a Vista windows. No problems with XP and not sure if it happens on all vista computers. How can I avoid having the customer (regsvr32)?
