You have not a copy of steam on another drive I had a steamold folder and it was detecting from there as well. Mine detecting correctly at this time .Expected version a tad old as well so seems same issue.
What VS version mine 6.6.108 ok I updated via reinstall to 16.0 R6 version of Livesafe Though VS should have been fixed mine was before I did this upgrade.
VS = vulnerability scanner.
No I was saying before I updated it was Ok as It seemed to fix itself for me It still is ok using the newer version. I will ask the techs. Note we are both on same VS version.
