Desktop App Web Viewer

Question

Hi All,

Can anyone tell me how to uninstall the Desktop App Web Viewer.  It is hijacking a person in our companies logins.  This is not associated with Adobe, already looked at that.

It has started popping up on their machine only when trying to login to Dynamics 365 App For Outlook with Dynamics 9.0 on premise.

Thanks in advance,

LLB

Answer 1

Hello all,

        We solved this prompt by removing Providers under Windows Authentication  on the main site. As we configured ADFS authentication hope this should be fine. Otherwise Microsoft need to update it. you can try too.

Answer 2

Hi Lbrownig,

Greetings. Based on your concern, I have done lots of research, but there is not any related official material about it. Since the Desktop App Web Viewer pops up only when trying to login to Dynamics 365 App For Outlook with Dynamics 9.0 on premise, it should be related to Dynamics 365 service, to better help you, we recommend you post a new thread in our dedicated Dynamic 365 forum for further assistance, the engineer there focus on researching Dynamic 365 service, believe they could offer you more proper method about how to uninstall it, thanks for your understanding and cooperation.

Regards,

Betty

Did you get answer to this?

Is this environment on Load Balencer for Front End servers?

Do you see errors on Developer Tools or Edge Dev Tools Preview with CORS?

Did you post this on any other site?

Very much interested with the outcome, we are also facing this isse after making changes to the SSL certificate on our servers.

Regards,

Joe.

Answer 4

HI Sushma,

No it didn't help, interestingly we found that the there is no prompt on another machine and this started to happen only after renewing SSL.

One of our network/desktop engineer looked at it and says that we need to include Subject Alternate Name for our Load balencer also as we are not using Wild card certificate. Requested for new certificate with IFD URLS, Front end, back end and deloyment servers and Load balencer URL as part of SAN and update you

Regards,

Daniel.

Hi, 

I was dealing with this issue for more than a month with MS support.

1. Perform this command to adjust the settings below on AD FS

 Get-AdfsProperties | select -expandproperty  wiasupporteduseragents

Set-AdfsProperties -WIASupportedUserAgents @("MSIE 6.0", "MSIE 7.0; Windows NT", "MSIE 8.0", "MSIE 9.0", "MSIE 10.0; Windows NT 6", "Windows NT 6.3; Trident/7.0", "Windows NT 6.3; Win64; x64; Trident/7.0", "Windows NT 6.3; WOW64; Trident/7.0", "Windows NT 6.2; Trident/7.0", "Windows NT 6.2; Win64; x64; Trident/7.0", "Windows NT 6.2; WOW64; Trident/7.0", "Windows NT 6.1; Trident/7.0", "Windows NT 6.1; Win64; x64; Trident/7.0", "Windows NT 6.1; WOW64; Trident/7.0","Windows NT 10.0; WOW64; Trident/7.0", "MSIPC", "Windows Rights Management Client", "*Edg.*")

2. Please follow this article to adjust the wiasupported user agents and let us know the result:

https://docs.microsoft.com/en-us/windows-server/identity/ad-fs/operations/configure-ad-fs-browser-wia

3. Please add the AD FS URL in the local intranet zone.

• select start > type inetcpl.cpl > enter
• select security > Local intranet > sites > advanced > enter in the AD FS address (https://sts.contoso.com) > add > close > OK > OK

4. go through this page

https://docs.microsoft.com/en-us/dynamics365/customerengagement/on-premises/deploy/post-installation-configuration-guidelines-dynamics-365#grant-application-permission-when-using-windows-server-2016-ad-fs

Also I received an advice that I should also do this(optional) except 3 mentioned above.

• On the CRM web front ends > open IIS Manager (start > run > inetmgr > enter)
• Expand server > sites > select CRM site > click on authentication in the main pane
• Select Windows authentication > advanced settings > providers
• Select the NTLM provider > remove
• Select negotiate provider > remove

5. DO NOT DISABLE integrated windows authentication (this is an error on MS page - if disabled SSO will not work)
