I have already seen that link. Two things about it
1. I am not getting any access errors to a temp folder as you can see in the image attached.
2. This only happens when I download using tabcmd and doesn't happen when downloaded through the server directly.
Considering both downloads are going into the same folder, I doubt this is a access issue
- Not sure why you are using so many versions of tableau in first place..version 10.0 ,10.5,10.5.3 ....
- secondly from the error message you quoted "I get the error "The load was not able to complete successfully" when trying to open the workbook." is related to permissions.Please check the below link
