This page describes computer, operating system, web browser, add-on, and network situations that can cause problems using the MapGuide Viewer. They are not problems for most users. If you are having a problem, though, one of these issues could be the cause. In addition, you may also want to review MapGuide Tips and Help.
New issue: 64-bit Internet Explorer is not supported. See 64-bit versions of Internet Explorer... below.
While the map may display on an unsupported configuration, some features of our maps do not work properly as these browsers are not supported by the MapGuide Viewer API (Application Programming Interface).
We hope that Autodesk will add support for these web browsers in future versions of the MapGuide Viewer.
We agree with our users who feel that MapGuide should work with Opera, Firefox, Safari, and other new browsers.
Browser compatibility is out of our control.
It's Autodesk's MapGuide Viewer software that doesn't support these browsers, not us.
There's nothing we can do to "fix" MapGuide to work with other browsers.
We support every browser and platform that Autodesk does
(and we support them better than most MapGuide sites with our MapGuide MWF Wrapper technology).
We don't lock out MapGuide viewing if it can work at all on other browsers, even though
some important features of our maps may not work.
Unfortunately, the fact is that Internet Explorer on Windows is the best choice for using our maps.
If you are getting a message saying a pop-up was blocked, the message box may give a hint of the program that generated it,
perhaps along the top edge.
The Google Toolbar is one example of an add-in that can be set to block pop-ups
but there are other toolbars that can block pop-ups,
including some you may not have realized are installed or you don't think would be involved.
You or someone else may have installed something or set something to be more "secure" but prevents things from working that you need to do.
Your web browser may be blocking pop-ups (See Your Internet Explorer security settings may be set too high below)
or your anti-virus/anti-spam software may be blocking pop-ups.
You may also be using security software or services provided by your ISP (Internet Service Provider).
The solution is to enable pop-ups or at least change to less-restrictive pop-up blocking settings.
The Google Toolbar should be removed. See the following item for more on Google toolbar problems.
While potentially risky, if you can't find what's blocking pop-ups, then you may want to briefly disable your Internet protection entirely as a short test.
Use the pop-up tests on our plug-ins page
to ensure your system is allowing "good" pop-ups.
Look for "Pop-ups" near the bottom of that page.
If you believe your firewall may be a problem using MapGuide,
have your network administrator enable access to:
You may want or need enable access to our other related webservers as well:
Also see the next McAfee security software problem with similar symptoms.
We don't have McAfee software and aren't knowledgeable in its use.
If you find a better workaround, such as disabling a certain McAfee feature through its user interface, or if you
have additional information or helpful experience with this problem, let us know using the webmaster contact on the Contact Us! page.
You may experience an access violation in the Google Toolbar when you close a window that contains an inactive ActiveX control.
Microsoft and Google technical teams have been working together to address this issue. Google is expected to fix this problem by
using its automatic "servicing mechanism" for Google Toolbar users. This problem affects Google Toolbar
versions before version 3.0.129.2. Visit the following Google web site to download the latest version:

The following compatibility issues are not problems for the vast majority of users:
You may also want to check out the Autodesk MapGuide Viewer Download and Installation FAQ (Frequently Asked Questions) in case you have a problem -- especially for details on Internet Explorer Version 6 and the "Cannot find the file 'MSIEXEC'" error message or problems with the Windows Installer service.
You may find (as we did) that the Autodesk FAQ and Microsoft Knowledge Base article it references are not helpful for the "Cannot find the file 'MSIEXEC'" installation problem. A few of our users have resolved this problem by copying selected files from another PC to replace missing files on the failing PC. Specifically, one user with Windows 98 Second Edition on two computers found the following files on another PC and copied them to the same location on the failing PC to resolve the problem:
c:\windows\system\msi.dll
c:\windows\system\msiexec.exe
c:\windows\applog\msiexec.lgc
These files names are for Windows 98 Second Edition. If you copy files, we strongly recommend that you copy them from an identical version of Windows. The files may be the same or different for other versions of Windows. We cannot endorse this solution or be responsible for the results.
