Hardball Viewer on Win7

[aussi1]

I am having problems running Hardballs Aircraft Viewer on my Windows 7 64bit PC. It ran fine on my old XP PC.

Initially I got a Can't start program as MSVBVM50.dll is missing from computer error so I downloaded and put this file in the same folder now I get a Component comctl32.ocx not correctly registered. file is missing or invalid error. The file is in the folder so where do I go from here? It appears to be a VB issue.

Is this a Windows 7 problem?
Will the program run on a 64bit system?
Anyone done this?
