Problem with Web Browser control in MS Access

I have an Access 2010 application that has a form containing the web browser control.  The web browser control displays a PDF file selected from a combo box.
This access database is located on a server.  I have two users that log into the network on separate computers and use this application.
For one user the form  works perfectly, displaying the selected file in the web browser control.  But when the other user selects a file a new Adobe Reader window displaying the file opens up over the top of the access form.
Why would this form work for one user and not the other?

Using the web browser control makes sense only if you want to display different file formats with it. If you know that only PDFs should be displayed, a PDF Reader Active X control is better suited - it allows for more control.
Aside from that, are you certain that Acrobat Reader is installed on both machines? The second one definitely has it installed, and set up as showing PDFs in the application instead of the browser control. If you open a PDF in a normal (IE) browser window, you wil have the same result.

I would disagree that it's better to use an ActiveX in the Access environment, and especially with 64-bit environments becoming the norm. Access has troubles with ActiveX controls, and those troubles have become much more significant in later versions. You're much better off using the Web Browser control to display the PDF files.

That said, as Qlemo suggests you need to insure the environments are correct on both machines, and that IE is setup to properly display PDFs on both machines.

Also - is this database shared by more than one concurrent user? By that, I mean the "frontend" portion that contains the Forms, Reports, etc. If that file is being shared by more than one person, then you will continue to have these sorts of issues.

Since the web browser is an integral part of Access and so easy to incorporate into forms I want to stick with it for displaying these files.
Adobe Reader is installed on both machines.  The machine that works is using version XI and the one that is not working is using version XI (11.0.09).   I have tested version XI (11.0.09) on my development machine and it works fine.
Scott, I'm not sure what you mean exactly by insuring that "IE is setup properly to display PDFs on both machines".  Again, both machines display the PDF.  It's just that the machine that is performing correctly displays the PDF within the web browser control  as it should and the other one displays the PDF in a separate window over the top of the Access form.
This database is not split into frontend and backend databases.  (It's on my list of things to do).  But that's really not coming into play here since only one person at a time is using it.

While there were several headline-grabbing ransomware attacks during in 2017, another big threat started appearing at the same time that didn’t get the same coverage – illicit cryptomining.

If you call a PDF in IE, does it display in IE?

I'm not at that site today but will have them try it and see what happens.
Can you tell me the specific IE setting that controls this?

I believe the IE Adobe Reader Add On was the problem.  I disabled it on my development machine and it caused the PDF file to display in a new window rather than the web browser control.  I re-enabled it and everything works fine.  I'll check this setting on my problem machine.  Thank you  both for the help.
