Me too (Windows 2000, msvcr71.dll missing).
Workarounds:
First, search for msvcr71.dll. If some other program has it in their folder, copy it to the Papagayo folder.
Alternatively, just do a Google search for msvcr71.dll, and download it (it's available from a number of sites).
Lastly, if you don't want to trust a general download site, download and install the .NET framework redistributable files from Microsoft (either via
Windows update or via
the developers download
Then, search for and copy the msvcr71.dll file into the Papagayo folder.
