_strupr() is cdecl, return ptr value in EAX
--- snip dlls/msvcrt/string.c ---
int CDECL _strupr(char *str)
{
    return _strupr_s_l(str, -1, NULL);
}
--- snip dlls/msvcrt/string.c ---
Because Wine returns/takes the status from 's' version instead of string ptr,
the app crashes.
MSDN: http://msdn.microsoft.com/en-us/library/sch3dy08.aspx
--- snip ---
Returns a pointer to the altered string. Because the modification is done in
place, the pointer returned is the same as the pointer passed as the input
argument. No return value is reserved to indicate an error.

You might want to check others too (_strlwr ...).
BTW .. the serial is from trial, no harm ;-)
