Cause

Some user groups do not have enough permissions on C:\windows\temp directory, thus, fails to create temporary files in there from services that need it.

Resolution

Add the necessary permission on C:\windows\temp:

1. Connect to the server via RDP;

2. Right-click C:\windows\temp\, go to Properties > Security (tab) > Advanced > select Users > click Edit, toggle the following two permissions:

   • Create files / write data
   • Create fodlers / append data

   

3. Check if there are any "Deny" rules for other groups
   

4. Switch them to "Allow"

5. Click OK.
