Why Do I Still Have Measurement Studio Evaluation Versions after I Purchased and Installed Measurement Studio?

Primary Software: Measurement Studio>>Visual Basic Support
Primary Software Version: N/A
Primary Software Fixed Version: N/A
Secondary Software: N/A

Problem:
I was using Measurement Studio ActiveX evaluation controls in my project, and then I bought Measurement Studio 6.0. I installed Measurement Studio, and then I opened my project. For some reason, my project is still using the Measurement Studio evaluation controls. What should I do?

Solution:
If you install newer, unlicensed versions of Measurement Studio ActiveX controls on a machine that has previously licensed versions of the Measurement Studio controls, the controls might exhibit one of the following behaviors:

  • The licensed controls become evaluation software for 30 days.

  • The licensed controls do not let you use functionality that was present in the licensed version.


Fix these states by using the Measurement Studio ActiveX License Fixer Utility located on your CD in the ActiveX License Fixer Utility folder. Refer to KnowledgeBase 2BTGHR56 (linked below) for more information about the license fixer utility.

If the license fixer doesn't work, you should try to delete the control from your project, drop it in again, and, if applicable, recompile. Sometimes there is a linking issue for controls in existing projects.

If that doesn't work, then the evaluation version is probably a newer version than the one included in your purchased version. You can try uninstalling the evaluation version before installing the purchased version.

Some symptoms of a newer version existing during an installation include either a message or a pause and apparent skip over a section of the full installation.

If some control still appears as an evaluation version, then you can find the particular files for the control that is reporting "evaluation version" and unregister and delete them before installing your purchased version. For this example, assume that you have this problem with the DataSocket control. You can follow these steps:

  1. Uninstall Measurement Studio.

  2. Find the names and locations of the ActiveX .dll files you need to delete. For DataSocket, the file you need to remove is nids.dll. For Measurement Studio ActiveX user interface controls, you need to remove cwui.ocx. These files are located in WINDOWS\system or WINDOWS\system32.

  3. Unregister the ActiveX control. Refer to the related link below, entitled: How Do I Manually Register Type Libraries, ActiveX Controls, and ActiveX Servers?

  4. Install your purchased version and test the controls that didn't work.
