Download and install OPCDAAuto.dll

Hello innovators! 

Before we start to build an OPC DA Client application, we need to install the OPC DA library first. This video shows you how to install OPCDAAuto.dll on your Windows system. 

This step is important because the library is not available on NuGet. And the OPC Foundation does not publish this one on the website any more.

So, make sure that you successfully install the library, because in the next tutorial we will use it to create an OPC DA client application.

Here are the steps:

1. download OPCDAAuto.rar from this link:

2. extract the file

3. Copy file OPCDAAuto.dll and if your Windows is:

3a. 32-bit then Paste to C:\Windows\System32

else

3b. 64-bit then Paste to C:\Windows\SysWOW64

4. open Command Prompt, and if your Windows is:

4a. 32-bit then type: cd C:\Windows\System32

else

4b. 64-bit then type: cd C:\Windows\SysWOW64

5. type: regsvr32 OPCDAAuto.dll

done!
