Both of the .NET scripts seem to cause my copy of apup2 to hang badly. They are the only scripts that seem to do this. And once the program un-freezes, I get the following error message almost without fail: "Invalid argument". And when I hit the "OK" button, apup2 closes itself.
One time, I was lucky to get the x86 script to download the entire copy of .NET. But that script only worked twice out of the 40+ times I attempted it. Really annoying. Plus I haven't even been able to get the x64 version to work once in apup2. All I get with the x64 script is the error message I mentioned above.
