Upgrade to Release 10.1.0

Upgrading to Toolkit 10.1.0 from previous versions requires explicit reference to the Toolkit core files for .NET.

Starting with TK 10.1.0, the core Toolkit files are no longer installed in the c:\Windows\System32 or c:\Windows\SysWOW64 folders. The files are now installed in the folder C:\Program Files\ActivePDF\Toolkit\bin. You must update your .NET application to explicitly reference the location of the Toolkit files. 

Additionally, if you reference the 64-bit DLLs in C:\Program Files\ActivePDF\Toolkit\bin\x64, go to your Visual Studio solution, and then to Build > Platform Target and uncheck the Prefer 32-bit box. Leave the platform set to Any CPU.

The following example is a code snippet to reference the Toolkit files located C:\Program Files\ActivePDF\Toolkit\bin\x64: 

APToolkitNET.Toolkit oTK = new APToolkitNET.Toolkit(@"C:\Program Files\ActivePDF\Toolkit\bin\x64");
