Instructions for Accessing RAAL Experiments with Different Browsers
1) Internet Explorer
In order to visualize the Experiment log-on screen and live images of the cameras (Experiment window)
in IE, certain ActiveX controls and settings need to be installed and configured on the browser.
Steps:
1. Open IE and make sure these options are enabled:
 Choose "Tools" then "Internet Options."
 Click on the "Security" tab, and choose "Trusted sites."
 Click on "Sites" and uncheck "Require Protected verification..."
 Add "sps.aerospace.utoronto.ca" and close this window.
 Click on "Custom level..."
 Scroll down the bar to get to "ActiveX controls and plugins."
 Make sure that EVERYTHING under this category is enabled.
 Click "OK" on all windows.
2. Go to Aerospace page www.aerospace.utoronto.ca, and log in AER303 (or AER304.) Select
Experiments tab and click on one of the experiment links. The Experiment window will pop-up on a
new page.
3. If the following message appears underneath the window “This webpage wants to run the following
add-on: Remote Desktop Services ActiveX Client from Microsoft Corporation,” select “Allow for all
websites” from the drop box.
4. If the following message appears underneath the window “This webpage wants to run the following
add-on: OCXDownloadChecker ActiveX Control Module from Geovision,” select “Allow for all
websites” from the drop box.
5. Finally, if the following message appears underneath the window “This webpage wants to run the
following add-on: LiveX ActiveX Control Module,” select “Allow for all websites” from the drop box.
6. If the Experiment log-on screen and live images of the cameras still do not show up as shown in
Figure 1, close the page and go to IE “Tools,” select “Compatibility View Settings”and add
“utoronto.ca” website for compatibily view. (For IE below IE11, click the compatibility view icon
located to the right of the URL bar.)
7. After doing the above, you should be able to see the Experiment log-on screen and live images of
the cameras as shown in Figure 2.

Notes:
If you still cannot see the Windows log-on screen on the Experiment page but you can see the live
images from the cameras as shown in Figure 3 after completing above steps, the problem is most likely
caused by an incompatible Remote Desktop ActiveX control.

A workaround to this will be replacing the incompatible RDP clients by the compatible ones. The steps
are described below. Make sure you backup your system files prior these steps in case the files become
corrupted.
a) For 64 bit OS
 Copy the compatible mstsc.exe and mstscax.dll files to the System32 and SysWOW64 directory,
respectively, on your machine.
C:\Windows\System32\mstsc.exe
C:\Windows\System32\mstscax.dll
C:\Windows\SysWOW64\mstsc.exe
C:\Windows\SysWOW64\mstscax.dll

Copy also the mui files (language files) for both to en-US directory.
C:\Windows\System32\en-US\mstsc.exe.mui
C:\Windows\System32\en-US\mstscax.dll.mui
C:\Windows\SysWOW64\en-US\mstsc.exe.mui
C:\Windows\SysWOW64\en-US\mstscax.dll.mui
b) For 32 bit OS
 Copy the compatible mstsc.exe and mstscax.dll files to the System32 directory on your machine.
C:\Windows\System32\mstsc.exe
C:\Windows\System32\mstscax.dll

Copy also the mui files (language files) for both to en-US directory.
C:\Windows\System32\en-US\mstsc.exe.mui
C:\Windows\System32\en-US\mstscax.dll.mui
To copy these files to the System32 and/or SysWOW64, you must have administrative privileges and full
control permission (modify and write) on mstsc.exe, mstscax.dll, mstsc.exe.mui and mstscax.dll.mui. By
default, administrator and users with administrative privileges on Windows 8, Windows 7 and Windows
Vista are not granted modify and write permission to System32 files for security reasons.
To gain full file access and write permissions from system user object (TrustedInstaller), which has
complete control over all system data, first you need to take the ownership of those system files by
modifying Advance Security Settings, and then you should be able to change the access permission to
take full control over those files. For further details, please visit the following link:

2) Mozilla Firefox
By default, Mozilla Firefox and Google Chrome web browsers do not support ActiveX controls. A
workaround to this will be to install third-party plug-in or add-on programs.
Firefox users can install Fire IE, this plugin makes it possible to use (host) ActiveX controls in Firefox and
provides full access to the hosted control.
Steps:
1. Go to this link https://addons.mozilla.org/en-US/firefox/addon/fire-ie/ and download Fire IE by
clicking the button “Add to Firefox.”
2. Install Fire IE by clicking “Install Now” as shown in Figure 4.
Figure 4
3. Restart Mozilla Firefox.
4. Go to Aerospace page http://www.aerospace.utoronto.ca/ and click on the word Fast or the
Thunderbolt icon located to the right corner of Firefox URL bar as shown in Figure 5.
Figue 5
5. A warning page will appear. Click Resume to start Internet Explorer engine to view current pages.
Figure 6
6. Aerospace page is displayed now with IE engine. After you log in AER303 (or AER304) page and open
any of the Experiments page, you should be able to visualize the Experiment log-on screen and live
images of the cameras as shown in Figure 7.
Figure 7
Note: The version of Mozilla Firefox tested is 31.0
3) Google Chrome
Google Chrome users can download IE Tab extension that acts as Internet Explorer emulator. It helps
enable ActiveX controls in Google Chrome as it emulates IE by using the IE rendering engine directly
within Chrome (Works only on Windows platform).
Steps:
1. Go to this link https://chrome.google.com/webstore/detail/ietab/hehijbfgiekmjfkfjpbkbammjbdenadd and add IE Tab by clicking the button “+ Free”.
2. A new page will open with an IE Tab icon displayed next to the address bar as shown in Figure 8.
Figure 8
3. You also need to install an application named “ietabhelper.exe” in order for the IE Tab to run
properly. By clicking the IE Tab icon, this application will be downloaded automatically, and then
run it.
4. Open a new tab and click the IE Tab icon to open or display an Internet Explorer address bar and
type in Aerospace page www.aerospace.utoronto.ca as shown in Figure 9.
Figure 9
5. Aerospace page is displayed now with IE engine. After you log in AER303 (or AER304) page and open
any of the Experiments page, you should be able to visualize the Experiment log-on screen and live
images of the cameras.
Notes:



This extension requires Internet Explorer to be installed on the same system, so it will not
work in Mac OS X and Linux.
If IE cannot display Experiment window properly, the IE Tab on Chrome will not display it
correctly either, since the IE Tab emulates IE by using the IE rendering engine.
The RAAL window sometimes minimizes by itselft.
