I usually download NetExtender onto Windows 7 but I have a few users with Windows 10 that need it. When I open it after download I get the error ' A damage version NetExtender was dectected on your computer, please reinstall to fix the problem!'
Acquisition Overview Dell has successfully completed the acquisition of SonicWALL, Inc., a leader in advanced network security, secure remote access, and data protection.SonicWALL’s industry-leading Next-Generation Firewalls and Unified Threat Management (UTM) Firewalls complement Dell’s security solutions portfolio, enabling it to offer customers a broader range of enterprise offerings.
I have reinstalled but nothing helped. I received this error before and just downloaded older versions of NetExtender.
However, now it is making me upgrade before using. The SonicWall site says the issue is 'Driver signing verification in windows 10 is causing the 8.6 net extender version to show as damaged.' How can I get around that issue? The problem appears to be with driver signing - SonicWall's current driver isn't recognized as a verified/signed driver by Windows 10, so the installer doesn't install the driver during setup.The way I got it to work without having to use the mobile app is that I found a Dell-driver version of the SSL VPN client that installed the Dell verified/signed driver in Windows 10 successfully (I used a version of the SonicWall NetExtender client with a digital signature date of 5-26-2017). After installation of this version, you can use and connect the NetExtender client without the 'Damaged Install' error. If your SonicWall device has newer firmware, you'll immediately be prompted to upgrade the client.
However, upgrading the client doesn't appear to replace the Dell signed driver, at least as of this post on, and the client should still connect properly.

It had worked fine before this, never had to update or anything. Now all of a sudden it starts throwing this error message out of the blue. So far I've uninstalled the client, deleted the path: C:Program Files (x86)SonicWallSSL-VPNNetExtender and reinstalled, still no luck. I've installed versions 8.0.241, 7.0.203, and 5.5.156, still no luck.
When I attempt to update the drivers and select choose from the list, I can confirm the drivers are digitally signed. I'm not sure what went wrong.
One thing though, right after the install sometimes I get a screen prompting for old password, new password for like 3 secs before it disappears and the error pops up.
