BTW, the good news is that I just tried again and it did work. The difference seems that it now said:
`Extracting nim-1.6.6_x64.zip` Instead of : `Extracting nim-1.6.6_x8.zip` The bad news is that Symantec Endpoint Protection immediately detected nimgrap.exe as a Trojan.Gen.2. @dom96, my IT department adviced me to install choosenim in a "safe folder" that is excluded from the antivirus checks. I tried to do that using --choosenimDir and --nimbleDir, but that does not work because choosenim does not remember the folders you chose (and thus forces you to explicitly use the same --choosenimDir and --nimbleDir flags everythime you call choosenim). Would you consider having choosenim save the latest choosenim and nimble directories that you used in some config file and reusing those automatically?
