[Wine] Problem installing/running program

[Nik]

Hello,

I am trying out wine to make a Windows program run under MacOS 10.6.6. It is a program for meteorlogical use with a rather small community. You can download it for free here (you won't be able to use it without account):

So I open the installation file with wine (1.2.2) and choose "run direcly in ...Wine Files"
The installation starts but in the end I get this error message:


> Self-registration error
> 
> One or more files did not prperly self-register.

> Following files did not self-register:
> 1. C:\windows\system32\bmplst32.ocx
> Module not found

> Module not found
> 
> 1. C:\windows\system32\Time32.OCX
> Module not found
> 
> To Continue select OK, otherwise select Cancel.

I hit OK and the installation finishes. But, of course, the program doesn't work. When I try to open the .exe with wine, I get this error message:


> 
> pc_met32
> 
> Component 'MRAS32.OCX' or one of its dependencies not correctly registered: a file is missing or invalid


Well, I am pretty new to Wine. From what I read, some Winetricks might help. But which ones, and how do I use them? When I select "Winetricks" in the menu, there is only an empty window. When I hit "Apply", I get the message "Winetricks was applied successfully" but noting more happens.

I have read the guide and FAQ but to be honest, I couldn't make much sense of it. Most of it refers to Linux.

Can someone help me?

Regards
