Version 5.04 is available here: www.opclabs.com/all-downloads/category/51-5-04 .

New versions are highly compatible in terms of API, I would not expect any problems using them. You can download the trial version for free.

Version upgrade costs are currently at approx. 50% of the new license price, you can view all the prices here: www.opclabs.com/purchase/full-price-list .

Best regards

Since on your previous email you mentioned that 64 bit is available from version 5.04 can you send me a copy of this install to licence & test?

I use very basic operation on QUICKOPC.NET (EG- Subscibe & Unsubscribe items, and some simple Read and Write Item Values. How compatible are later versions of QUICKOPC with this functionality. In other words are there any drepecated functions from 5.02 to 5.31?

I would like to upgrade to higher version but have not included this as a cost in my project? Are there now licence upgrade costs?

Your license should work for all versions that start with 5.0 (e.g. 5.00, 5.01, 5.02, 5.04). It will *not* work with versions that start with 5.1, 5.2, 5.3 etc.

OK Thanks. We do not do many projects with OPC hence the large gap in QUICKOPC version implementation!

Some Questions
  • We currently have a Multi-purpose developer licence Serial # - 1050020013.bin. Will this work on all later versions of QUICKOPC.NET or should i download a specific version?

Version 5.02 does not support running in a 64-bit process. This is available from version 5.04 (we are currently at version 5.31!)

Recommended approach is to upgrade QuickOPC. Your version is no longer supported anyway.

If you have to stay with version 5.02, you can try to force it into 32-bits like this:

a) For applications that you build yourself in Visual Studio, change the project platform from "AnyCPU" to "x86".

b) For application where you only have the binary (.EXE) available, use CorFlags utility ( msdn.microsoft.com/en-us/library/ms164699%28v=VS.100%29.aspx ) .
