I'm getting the same issue. I've tried multiple times. My internet connection is NOT lost. I could be watching youtube, netflix, or downloading a huge file while this thing is installing and it always gives this error. Is Dell the one that lost internet connection? Maybe it needs to phone home and it's calling a disconnected number (IP for this case)?
I have the exact same problem. Yesterday I tried opening SupportAssist because I needed to know my service tag, and couldn't find it anywhere. I then checked the installed programs and it was there, including the folders under Program Files\Dell\Support Assist.
So I uninstalled everything, trying downloading the 3 same files you mentioned, same error. I'm in contact with a Dell rep over twitter due to some other issues, so I thought of reaching them out. One of them remotely connected my pc, and tried over several things, and also he couldn't fix it.
Dell can cease to amaze me. How come they publish a version of an application that can cause so many problems. Where's quality assurance on this, for gods sake???
There are two scenarios we've been using to solve this issue, if either one do not apply then it be best to contact Dell Support, each case can be different. Also these steps are only good for latest release of v2.2.3.2, if the version is different going forward you would need to grab the correct files from the location below.
Installation cancelled - We encountered an unexpected error while installing SupportAssist. This may be due to a lost internet connection. Check your connection and try again.
Complete the following steps to fix this issue:
Press the Windows Logo key + “R”
Type %programdata% and press Enter
Delete the following folders:
PCDr
PC-Doctor, Inc
SupportAssist
Press the Windows Logo key + “R”
Type %appdata% and press Enter
Delete the “PCDr” Folder
Go to the folder “C:\Program Files\Dell\”
Delete the following folders:
SupportAssistAgent
SupportAssist
Press the Windows Logo key + “R”
Type regedit and press Enter
In the Registry Editor Delete the following registry keys:
Wait a few minutes to ensure SupportAssist is installed and appearing in “Control Panel\Programs\Programs and Features” , notice the size will be ~ 10MB.
Wait for the installer to install DDV services. Ensure all DDV services are running & SA Agent service is running. Example screenshot:
Important:
Modifying the registry may cause the operating system to fail if it is not properly done.
Ask the customer to backup any sensitive data before going through the steps above.
Preferably, the steps above are to be performed using DellConnect
Scenario 2:
Error message encountered during installation:
Installation cancelled - We encountered an unexpected error while installing SupportAssist. This may be due to a lost internet connection. Check your connection and try again.
InstallShield 18:51:19: Failed to apply permissions for object 'MACHINE\SOFTWARE\DELL\SupportAssistAgent', error 0x80070002
Go to path c:\Program Files\Dell\SupportAssistAgent\bin folder path, check if it has “.TMP” files in it. (refer to the following screenshot)
Open Windows Services (search "Services.msc") and verify “Dell SupportAssist” service is running.
If all above steps are validated with the screenshots & error messages as specified , Please use following workaround steps to fix the “Installation” issue.
Ok, thanks, looking forward to receiving some news... even if the previous version of SupportAssist was working great even on Windows 1083 version 17314...
Hello, just wanted to update about this issue. The problem is still present on the latest available Windows 10 build (1809). Is there an ETA for this fix? Thanks, Michele
I am still experiencing the exact same issues. When I try to update to the latest version from the Dell website
for my dell xps 8900. I get the message 'Installation cancelled we encountered an unexpected error while installing SupportAssist this may be due to lost internet connection'
I am using version 2.0.6875.668 which I have been able to reinstall, it still works.
When opening the program it does start to download the update and I get the message update complete but the program just will not update. Ive tried everything including uninstalling with Revo Uninstaller, nothing appears to work. Dell please fix this program.
SupportAssist installation doesn't required manual intervention so no UI interface is required. Based on screenshots SupportAssist installation already done for you. Can you check the installed size of SupportAssist under program and features. In case SupportAssist installed size is more than 100MB that means installation is successful and you can use SupportAssist properly. If you can not able to find SupportAssist shortcut on your system then try below work around steps:
Workaround solutions: =================
Solution 1: --------------- 1. Open command prompt as administrator and run "cd C:\Program Files\Dell\SupportAssistAgent\bin" 2. Now run "SupportAssistUI.exe launch"
Solution 2: --------------- 1.Ensure Internet explorer browser version is 10 and above. (Internet Explorer > Settings > About Internet Explorer).
2.Delete Internet Explorer Browser Cache then retry launching SupportAssist. (Internet Explorer > Settings > Safety > Delete browsing history).
3. Open IE and got to Setting > Internet Option > Security > Internet and set "Security Leve for this Zone" as 'medium high'
4. Open Windows registry (Start > Run > regedit), ensure registry path [HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION] has value as "SupportAssistUI.exe"=dword: 00002af9 (11001) or (10001)
5.Open “Control Panel\System and Security\Windows Firewall\Allowed apps, ensure “SupportAssist” is in the “Allowed apps list”. If it is not in the list, add it by clicking on “Change Settings” then click on “Allow another app” – point it to the path “C:\Program Files\Dell\SupportAssistAgent\bin\SupportAssistUI.exe” After adding “SupportAssist” in allowed apps, reboot the system so that firewall changes are reflected.

Does Dell Support even look at these posts?

Hi,
These few steps might help anyone
- If you are at work, turn the proxy off and try installing the support assist
- Or try hotspotting through your phone and install it.
