Problems Installing Windows Defender?
Microsoft has offered up a fix for users who are encountering "Error 1609" when trying to install Windows Defender Beta 2, attributing the problem to the lack of a local group named "Users."
This group often has a different name in international versions of Windows, the company says.
A knowledge base article has been added to Microsoft's Support site to instruct users on how to correct the issue so that Windows Defender installs properly.
A new version of the software that does not require a workaround will be released shortly for those who wish to wait, Microsoft said.
1. Create a new local group named "Users." To do this, click Start, click Run, type net localgroup Users /add, and then click OK.
2. Add the non-English language local Users group to the new Users group that you created in step 1. To do this, follow these steps:
a. Click Start, right-click My Computer, and then click Manage.
b. Expand Local Users and Groups.
c. Click Groups.
d. Right-click the Users group that you created in step 1, and then click Add to Group.
e. Click Add, type the object name of the non-English language local Users group, and then click OK two times.
3. Try to install Windows Defender Beta 2 again.
