The problem is, that your users "target" machine misses the msvcr80.dll file (contained in vcredit_x86.exe), that your plugin depends on - but Wireshark itself not (so Wireshark won't provide it).
The actual required DLL depends on your compiler (exactly: C-Runtime) version compiled, for example Visual Studio .NET 2002 will need msvcr70.dll (the devel guide gives some details on this).
Please note that this is a problem common for all programs, not only Wireshark. The binary must provide the C runtime DLL that it was compiled with.

As the support for MSVC != 6 is currently experimental, don't expect this soon - we really need some more experience with it first.
First of all, mixing binaries will only work if the plugin is "safely" developed, e.g. it don't passes file handles to other plugins or the Wireshark core - I don't know it this is currently the case for all plugins.
Secondly, even if we would release Wireshark compiled with the 8.0 compiler, we would still have similar problems with plugins compiled with other C compiler Versions (7.0, 7.1, 9.0, ...).
In general: It's not such a good idea to mix binaries coming from different compiler versions.
You may think about providing your own Wireshark setup together with your plugin for now ...
