I was able to get 5.10 installed.
On our other machines, using slightly different ConnectX-3 cards (OEM versions), we had a similar problem, where we couldn't install the latest versions of the driver, but could install 5.10. I mean, they're working fine, but isn't this an issue? We're now seeing it on there different Windows 7 machines (two Ultimate, one Pro), with two different ConnectX models.
Ok, so someone marked this answer as "correct" -- but it's not an answer.
Can you run the latest drivers on this card in Windows 7 or not?
Almost same problem.
I have ConnectX-3 Pro card, windows 7 prof. x64. downloaded driver: http://www.mellanox.com/downloads/WinOF/FUR/MLNX_VPI_WinOF-5_35_All_Win7_x64.exe
Installer fail with error that 3033929 update not installed. But it's not truth. I have this update (I have all of them). I tried to install 3033929 manually, but it's said that already installed.
I think, I have not directly 3033929, but some of convenience roll-up updates, that include 3033929.
What can I do to install drivers? May be installer have some switches to skip this check?
