[This discussion has been continued via email. The likely reason for the problem was that the license file was for versions 5.22-5.39 while the version being used was 5.20.]

Can you please take a snapshot of the License Manager screen, with the license installed, and either post it here, or send by email to sales09(at)opclabs.com, replacing (at) by @.

This is probably the cause. License for 5.1x won't work with versions 5.2x.

If you have purchased a 1-year maintenance agreement with your QuickOPC 5.1x, and if version 5.20 was released during the validity of your agreement, we will send you a license for all 5.2x versions, free of charge. In such case please identify yourself (e.g. using the license serial number).

If you do not have a maintenance agreement or if versions 5.2x do not fall into its validity period, and you want to use 5.2x or later, you need to purchase a Version Upgrade.

Best regards

Actually, it should be after 30 minutes.

The error code corresponds to:

Run time is over the limit. The license you have (most likely trial version) does not provide valid data after certain time period expires. Note that after the component's process is simply restarted, valid data will be provided again, and so over. Obtain and install proper license to permanently resolve this error.
