Rollback error when trying to install on Windows 10

What is the Windows OS build (from the command line commands: winver or systeminfo) and FortiClient version?

Hello everyone,

Same issue as above.

I have read the other posts on the forum about this issue and have tried the suggestions but still no luck. The installer will get to a certain point 'Installing drivers' then roll back. There are no fortinet adapters or registry entries but the installer cannot complete.

I can only assume it is finding a remnant of the previous install and will not finish. Is there any other option to get this installed on windows 10?

Thanks in advance folks,

M.

Hello,

I've the same problème with Windows 10 version 1709 64 bits.

I can't install the last version of Forticlient.

Thanks for your help.

I also have this problem.  As a workaround we first run FCRemove.exe to do a clean uninstall of FortiClient then we run the 5.6.5 install of FortiClient.  I would love to see Fortinet stop doing rip and replace upgrades and start doing in place upgrades for FortiClient.
