For upgrade, if you have MS Visual Basic 6 or msvbvm60.dll, you can just download polarexe.zip, but you need msvbvm60.dll and comdlg32.ocx in the same directory as polar.exe or in the directory \windows\system for Windows 95, or in the directory \winnt\system32 for Windows NT/2000.
Microsoft Visual Basic 6 runtime DLL files are from http://www.simtel.net/simtel.net/win95/dll.html, where msvbvm60.dll is inside simvb6-5.zip. And download comdlg32.ocx 6.0.84.18 in 1999 May 7 here.Country URL (host and directory path) --------- ------------------------------------------------- Australia http://www.drhuang.com/science/chemistry/electrochemistry/polar.zipAfter download, please double-click the race.zip file with Winzip, and then double-click the setup.exe file to setup.
