Collatz Sieve v1.21 released for Windows
The validation bug is now fixed but some have reported that the application errors out immediately. If you run into error -1073741515, please try installing the latest VS2012 C++ runtime available from Microsoft at https://www.microsoft.com/en-us/down....aspx?id=30679. VS2012 was recently updated to SP4 on my laptop and that is likely the cause of the missing DLL error.New versions for Linux and OS X will be forthcoming as soon as I figure out how to get the VMs used to build the Linux versions to route properly through the VPN pipe on my laptop and since it is Labor Day weekend, I'm trying not to work too hard.
