In this topic:

Q: What are the evaluation version limitations?

Evaluation version has two limitations:

  • Trial message is displayed before each upload.
  • It stops working after a 60 days period.

Evaluation version of Aurigma Image Uploader Dual is fully-functional. None features are blocked. No upload size, file count, file type restrictions are applied (unless you configure it as described in the Configuring Restriction Rules for Files) section.

Read more about an evaluation version of Image Uploader in the How to Evaluate Image Uploader topic.

Q: I have just downloaded Aurigma Image Uploader Dual but it does not work. What should I do?

Please be sure to learn about the changed trial licensing policy. From now on, you will need a trial license key to test-drive the trial version (except for localhost). For details, see How to Evaluate Image Uploader topic.

Q: The evaluation period of Image Uploader has been expired. How do I evaluate it some more time?

If the 60 days evaluation period expired before you completely evaluate Image Uploader, or when you are using a trial version for the development purposes, you can prolong this period using one of the following ways.

Use Image Uploader Trial License Keys Request Tool

This tool is included in Image Uploader SDK and is very simple to use. All you need is to run this tool and enter your e-mail and password you are registered on Aurigma with.

Prolong Evaluation Period Online

If you cannot obtain trial license keys using Image Uploader Trial License Keys Request tool for some reason you can do it online (

Then paste obtained keys to your application in accordance with a way used to embed Image Uploader. Thus, in the case if you use the ASP.NET control find the detailed instructions on how to insert license keys in the Configuring Image Uploader ASP.NET Control topic. The Configuring Image Uploader PHP article shows how to perform the same task using the PHP library. And the Configuring Image Uploader topic describes how to do it using JavaScript. This way you will be able to continue working with Image Uploader until the evaluation period of the new trial keys expires. Read additional details in the How to Evaluate Image Uploader topic.


If you have purchased Image Uploader and use an evaluation version for development, but limitations of evaluation version are not acceptable for you, please contact us for getting development license keys.

Q: How do I turn evaluation version into full one?

Upon purchase you should get a full license key, which is based on a domain name or IP address you buy it for. You should use this license key as described in the Removing Limitations of Evaluation Version topic.

There is no need to download any kind of "full" version. Just use the full license key instead of the trial one.

Q: I have inserted a license key, but I get the message that no valid license key for current DNS/IP address is specified. Why can it be?

There are two reasons are possible:

  1. Domain name or IP address of a website where you host Image Uploader differs from the domain name or IP address you purchased a full license key for.
  2. Files are uploaded to the domain name or IP address which is not registered with full license key.
  3. License key (full or trial) is inserted incorrectly for some reason. For example, it may happen because of some misprint or extra character in the license key.
  4. Non-Dual version Image Uploader (ActiveX or Java) is used but both versions are enabled in Image Uploader settings. This way you should disable the version you have not purchased license key for. For example, if you purchased ActiveX version only, disable Java, and vice versa. To do it, set the activeXControlEnabled or javaAppletEnabled property to false.
  5. Evaluation period (if trial license key is used) has been expired. If so, you should purchase a full key or prolong the evaluation period.

Q: I have purchased the Dual version, and got two license keys. How should I insert them properly?

The correct way to insert several license keys is to put one after another separated with semicolon, and insert it in the same way as you do for a single license key, like this:


See the LicenseKey property reference for more details on this.


Do not try to insert it as two (or more) LicenseKey parameters. Only one the last one will work, and only one license key will be applied.
