Should I use the .NET 4.0 or the .NET 2.0 DLLs?

QLM provides several sets of .NET DLLs that are located in these folders

C:\Program Files\Soraco\QuickLicenseMgr\Redistrib\netx

QlmControls.dll

QlmLicenseLib.dll

QlmLicenseWizard.exe

The following table shows which version of .NET is preinstalled on Windows and which QLM DLL to use in each case. You can find the full article here.

For example, if you install your application on a Windows 8.1 operating system, it is preferred to use the QLM .NET 4.0 DLLs. However, you can still use the .NET 2.0 DLLs on Windows 8.1 if you install .NET 2.0 (or 3.0 or 3.5) on the customer's system.
