For test with macros can I install the basic and standard version in the same computer?
In different directories, yes, no problem
But… keep in mind that the last WM you ran, will be the one used when opening a TMD file. So if you run the Basic Edition, then close it, and then double click on a tmd file, that file will be opened with the Basic Edition. If you do that with the Standard Edition, the file will be opened with the Standard Edition… You will also have the “recently opened files” list shared between both apps, though. But everything else should work fine!
