WS V1.8.2 on win server 2003, msvcr100.dll issue!

Hi

I have installed Wireshark version 1.8.2 (SVN Rev 44520 from /trunk-1.8) on a new win server 2003.

I can open a large (previously captured) packet capture file ~ 600MB, without any trouble.

When I select "Telephony" - "VoIP Calls", I get a progress screen. This stalls at about 60%, and 30 sec later wireshark ends.

Event log shows: Faulting application wireshark.exe, version 1.8.2.44520, faulting module msvcr100.dll, version 10.0.40219.1, fault address 0x0008d6fd.

I have tried installing the "Visual C++ 2010 x86 Runtime Lib W/SP1" and replacing msvcr100.dll (in the wireshark dir), from version 10.0.40219.1 too 10.0.40219.325.

Any thoughts?

Many thanks,

Simon
