Q [ActiveX]: ActiveX version of Image Uploader fails during installation: red cross is displayed instead of the control. Why?
The can be several reasons:
Too Strict Security Settings
Internet Explorer can be configured to prohibit installation of ActiveX controls. Typically this configuration is default on server editions of Windows (like Windows 2003). Also, in some corporate networks it can be defined with the security policy.

Default security settings on workstations (like Windows XP) allows installing signed ActiveX controls. |
To check whether security settings are ok, follow these steps:
- Open Tools -> Internet Options menu in Internet Explorer.
- Switch to Security tab.
- Click Custom Level button.
-
Make sure that:
- The Download signed ActiveX controls radio button is Prompt or Enable.
- The Run ActiveX controls and plug-ins radio button is Enable or Prompt.
- The Script ActiveX controls marked safe for scription radio button is Enable or Prompt.

These steps are written for Internet Explorer version 6. In other versions menus and buttons may slightly differ. |
Firewall Software
Some firewall software may be configured to block any ActiveX controls met on the page the user loads. If you have some firewall installed, check out its settings or contact your system administrator regarding this problem.
Incorrect Path to ImageUploader5.cab File
To install Image Uploader on client machine, Internet Explorer downloads the ImageUploader5.cab file. You should provide correct URL to this file, otherwise Internet Explorer will fail to download and install it.
URL to this file is specified in the codebase of the control. If the iuembed.js script is used, this is configured with the activeXControlCodeBase property. It can be both absolute and relative URL. Make sure that ImageUploader5.cab is accessible from this URL.
Corrupted CAB File
ActiveX controls should be signed with a digital certificate to be interpreted as safe by Internet Explorer. In theory it is possible to enable unsafe ActiveX controls, however it is not recommended as it may compromise security.
Image Uploader is already signed with Aurigma's digital certificate (speaking more precisely, the ImageUploader5.cab file). However if you modify this file anyhow, e.g. rename or re-assemble it, the digital signature will not be valid. This way Internet Explorer will interpret this file as unsafe and reject to load it.
Error During Installation
Although Image Uploader is thoroughly tested on different environments and should work in all supported versions of Windows, potentially it may suffer from lacking dependencies or similar problem. To troubleshoot this, follow steps described in this Knowledge Base article:
Q [Java]: Java Version of Image Uploader fails to be installed. Why?
Several reasons can cause this problem:
Java Runtime Environment Is Not Installed
Java version of Image Uploader requires Java Runtime Environment (JRE) version 1.4 or later. If it is not installed, no Java applet will run.
Java Applets Are Disabled in Browser Settings
Most browsers allow users to disable Java applets. Make sure whether Java applets are enabled in your browser settings (varies from browser to browser).
Certain Mac Browsers Require Additional Plugins
If you experience problems with Java version installation on Mac, keep in mind, that some Mac browsers do not support JRE 1.4 by default. To have these browsers to work with JRE 1.4, it is necessary to install additional plugins:

The following Mac browsers already have built-in JRE 1.4 support:

Q [ActiveX]: ActiveX version of Image Uploader works in Internet Explorer only. Is it ok?
Yes. The only browser that supports ActiveX technology is Internet Explorer on Windows. No other browsers can work with ActiveX controls (including Internet Explorer for Mac). Use Java version of Image Uploader with these browsers. If you are using iuembed.js script to work with Image Uploader, it will automatically detect the user's browser and load appropriate version.
Q [Java]: Are there some browsers that are not supported with Java version of Image Uploader?
Yes. The following browsers are not supported:
- Internet Explorer for Mac.
- Opera (all platforms).
See a list of supported browsers for more details.
Q [ActiveX]: Is there any way to install Image Uploader manually rather than through the browser?
Yes. You can download standalone installer at this location:

Although standalone installer allows to install Image Uploader regardless to Internet Explorer settings, the user still needs administrator privileges. |
Q [ActiveX]: Image Uploader is loaded on one computer, but cannot be loaded on another. Security settings are ok. Why can it be?
Most likely the problem is in incorrect codebase.
This situation has the following explanation. ActiveX controls are cached by the browser. Once it is downloaded and installed, stored on client computer. If on the first computer you visit online demo of Image Uploader or load it anywhere else, Image Uploader gets into the browser's cache. Internet Explorer will not try to download it and therefore incorrect codebase will not cause any problems.
However as soon as you try to open the page from another computer, which never downloaded Image Uploader, Internet Explorer will try to download it from the codebase, and of course it will fail.
Q [ActiveX, Java]: How can I update or remove Image Uploader from browser cache?
See the Updating Image Uploader on the Client Side topic.
Q [ActiveX, Java]: I want to see my company name instead of Aurigma on the security dialog during installation. How can I do this?
You need to order a private-label version of Image Uploader. Contact our sales department for more details.
Q [ActiveX]: Sometimes, when I update Image Uploader, a message prompting to restart computer is displayed. Why?
If you get this message when updating Image Uploader in the browser, it means that you have another browser instance with Image Uploader opened. In this case it locks the old version of Image Uploader. That's why old version fails to be uninstalled and the browser prompts to restart computer to complete installation.
To avoid this problem, it is recommended to close all browsers that host Image Uploader before updating it.
Q [ActiveX]: Installation dialog displays "Unknown Publisher" instead of "Aurigma". Why it can happen and how to avoid this?
Most likely you have modified the ImageUploader5.cab anyhow (e.g. renamed it or changed some files inside it), or it was corrupted. It have made the digital signature invalid. That's why the browser interprets this CAB file as unsigned.
So if you encounter this problem, download Image Uploader Aurigma website again and update the
ImageUploader5.cab
file on the server.
Q [ActiveX, Java]: I am using old version of Image Uploader (purchased earlier than one year ago). Can I install and use new version?
Although Image Uploader has been built as backward-compatible as possible, if you are using Image Uploader of previous generations, you should make certain changes in your code. They are described in the Upgrading from Previous Versions section.
Also, keep in mind that license keys for previous major versions are not compatible with new version. You should purchase an upgrade. Feel free to contact our sales department if you have any questions regarding this matter.
