Something prevents Envdir to properly install the files in this folder. This could be caused by:
- Not running Envdir as an admin : check in the shortcut or exe properties you are always running Envdir as an admin
- Windows user account control : check that it is disabled
- An antivirus program : Please check that you have put an exclusion for Envdir.exe or try to temporarily disable the program when using Envdir to see if this helps.
