What eSellerate files are installed on my computer?

eSellerate Files and Information Stored on the Local Computer

eSellerate is an e-commerce provider that handles online order processing for many different companies that sell their products online. We at eSellerate provide code to developers to incorporate into their software, which will allow for product registration/activation functionality. As a result, any of our clients' applications may install files on your computer for the sole purpose of handling purchase, update and registration functionality.

The eSellerate files are in no way malicious and cannot be used to obtain or report information about you. No personal information is stored in the files, except as specifically described below. When one of our clients' applications makes a call to purchase, check for update, or activate (register), the eSellerate files are used to handle those processes in a very secure manner. All information is encrypted and passed through a secure connection directly to eSellerate's servers. eSellerate has an excellent record and has one of the lowest fraud rates in the industry. We are required to maintain strict security polices to remain compliant with standards set by the various credit card companies and maintain PCI (Payment Card Industry) Compliance.

On Macintosh systems, the following eSellerate files may be installed:

  • EWSMac.framework
  • EWSMacCompress.tar.gz
  • eSellerateEngine (Carbon)

On Windows systems, the following eSellerate files may be installed:

  • eWebClient.dll
  • eSellerateEngine.dll
  • eWebControl365.dll
  • eSellerateControl365.dll

Macintosh File Descriptions

The eSellerate framework, which actually handles the purchase/update/registration functionality, is either called EWSMac.framework or else eSellerateEngine (Carbon), depending on which method the developer used to include the eSellerate functionality in the application. EWSMacCompress.tar.gz is simply the compressed version of EWSMac.framework, which has a smaller file size to make the product's installation files smaller. If you have installed more than one application that uses eSellerate's technology, it is possible that any or all three of these items might be present on your computer; having more than one of these is normal and will not cause any problems.

Macintosh File Locations

The optional compressed EWSMacCompress.tar.gz may be found in ~/Library/Application Support/eSellerate. The framework will be decompressed and installed as EWSMac.framework prior to being used.

EWSMac.framework will either be installed to /Library/Frameworks if permissions allow, or else ~/Library/Frameworks if there are insufficient permissions to write to /Library/Frameworks.

eSellerateEngine (Carbon) will be installed to /Library/Application Support/MindVision if permissions allow, or else ~/Library/Application Support/MindVision if there are insufficient permissions to write to /Library/Frameworks.

Other Macintosh Files

Upon successful registration/activation, a small plain text file is written to /Library/Application Support/MindVision (or else ~/Library/Application Support/MindVision). (Note that MindVision Software is the parent company of eSellerate.) This text file simply acts as a flag to let the software know that the activation was successful so that you are not prompted upon each launch to register again. The information stored in the file is useless to anyone else and does not contain sensitive data.

Also, if you make a purchase from within a software application that uses eSellerate's code, rather than through a Web Store, a small plain text file is stored on your machine containing your name, address, e-mail address and telephone number. This is only used for the purpose of saving you time in future purchases. It allows the application to pre-fill the fields in the purchase screens with that information. The file is called com.esellerate.ewsmac.plist and can be found in ~/Library/Preferences. This file does not contain any credit card information, and if it is deleted it will not cause any problems because it is not required in any way.

Windows File Descriptions

The eSellerate engine, which actually handles the purchase/update/registration functionality, is either called eWebClient.dll or else eSellerateEngine.dll, depending on which method the developer used to include the eSellerate functionality in the application. Similarly, eWebControl365.dll and eSellerateControl365.dll are two different versions of an ActiveX Control that interacts with the eSellerate engine in some installations. If you have installed more than one application that uses eSellerate's technology, it is possible that any or all of these items might be present on your computer; having more than one of these is normal and will not cause any problems.

Note: You may also have older versions of the files on your computer, such as older versions of the ActiveX Control. For example, you might have eWebControl350.dll instead of eWebControl365.dll.

Windows File Locations

Unlike on Macintosh, many of the eSellerate files for Windows are not required to be in a specific location on your hard drive. The developer of the application can install the eSellerate files anywhere on the machine, although there are some default locations that will be used unless the developer specifically chooses to install the files elsewhere.

For eWebClient.dll, the default location is C:\Program Files\Common Files\eSellerate\eWebClient.dll on Windows NT, Windows 2000 and Windows XP. On Windows Vista, the default location is C:\ProgramData\eSellerate\eWebClient.dll.

For eSellerateEngine.dll, the default location is C:\Windows on Windows NT, Windows 2000 and Windows XP. On Windows Vista, the default location is C:\ProgramData\eSellerate\eSellerateEngine.dll.

For eWebControl365.dll, the default location is C:\Program Files\Common Files\eSellerate\eWebControl365.dll on Windows NT, Windows 2000 and Windows XP. On Windows Vista, the default location is C:\ProgramData\eSellerate\eWebControl365.dll.

For eSellerateControl365.dll, the default location is C:\Windows on Windows NT, Windows 2000 and Windows XP. On Windows Vista, the default location is C:\ProgramData\eSellerate\eSellerateControl365.dll.

Windows Registry Entries

Upon successful registration/activation, an entry is written to the Windows registry in two locations:

  • HKEY_LOCAL_MACHINE\SOFTWARE\eSellerate\Activations
  • HKEY_CURRENT_USER\Software\eSellerate\Activations

The contents of the registry entries simply act as a flag to let the software know that the activation was successful so that you are not prompted upon each launch to register again. The information stored in the entries is useless to anyone else and does not contain sensitive data.

Also, if you make a purchase from within a software application that uses eSellerate's code, rather than through a Web Store, a separate registry entry is created containing your name, address, e-mail address and telephone number. This is only used for the purpose of saving you time in future purchases. It allows the application to pre-fill the fields in the purchase screens with that information. The entry can be found in HKEY_CURRENT_USER\Software\eSellerate\Common\PurchaseInfo. This file does not contain any credit card information.

IMPORTANT:  eSellerate does not recommend making any changes or edits to your Windows registry. If you make a mistake or change the wrong item, your computer may cease to work. We cannot assist you in making any changes to your Windows registry, and eSellerate will not be responsible or liable for any damages of any type arising from making any type of edit to your Windows registry.


eSellerate takes your privacy seriously. You can find our detailed Privacy Policy here, and our Product Activation Privacy Policy here.
