If you would like to use the old version (which had less features but was simpler and required .NET 3.5 rather than .NET 4.0) then you can use the following link to download a ZIP file containing the old version files.
Note that this is not an installer - providing you have already got .NET Framework 3.5 SP1 installed then you can just extract all files from the ZIP file to the same folder and then run the program from there: ADTidy.zip
