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.
Make sure that you are using the appropriate serial number for your license version before running the 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. Make sure you run the installer as Administrator and retry the License Fixer Utility.
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:
- Uninstall Measurement Studio.
- Unregister the problematic ActiveX control(s) using
- Select Start»Run.
- In the dialog box that appears, type
regsvr32 /u [Full path of .ocx file], where [Full path of .ocx file] is the location of the
.ocx file. The
.ocx file should be in the
C:WINDOWS\system32folder. If you have a 16-bit control, you can run
regsvr instead of
- 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
- Install your purchased version and test the controls that didn't work.
