Thank you
There was an error in the .NET application and the OPC Address string was incorrectly specified.
NOT a QuickOPC error!

Another question

The software using the Easy OPC 5.03 is compiled to target .NET Framework 3.5 SP1. We are attempting to upgrade the PC from Windows XP to Windows 7. Windows 7 has .NET Framework 4.6.1 installed.

NOTE: The .NET software opens and appears to work but it seems that communicating with the my MX OPC Server, via EasyOPC is throwing exceptions.

Is there anything that would cause this?

Thank you.

The license keys for QuickOPC are not distinguished by whether they are for 32 or 64 bits.

But anyway, if you are having problems with the license, you can clean it up completely like this:

1. Start REGEDIT.

2. Delete the HKEY_LOCAL_MACHINE\SOFTWARE\Licensing\QuickOPC 5.x key, if present.

3. Delete the HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Licensing\QuickOPC 5.x key, if present.

(5.x would be 5.0 for your version)

Best regards

Good day,

We have in error used a 64-bit license to licenese our 32 bit QuickOPC.NET installation.
When we try to unistall the 'wrong' license we cannot - See attachment for error when trying to uninstall the 64 bit license!

We have installed QuickOPC.NET version 5.03.446.1.

Thank you.
