License issue for asp/vb.net web site

[davidacohens]

I just purchased on-line the Spire.XLS version 12.1.7.5040 product for my development machine.
You sent me the xml license file

I am trying to use this on my web site (developer machine) using asp.net/vb.net.

I have tried just putting the license file in the bin directory where the Spire.xls.dll is. And when I attempt to create a spreadsheet with 8 tabs, it gives me 5 tabs and the Evaluation tab.
I then tried putting the Spire.License.LicenseProvider.SetLicenseKey)() in the Global.asax, application start routine and copied the entire node of the License key from the file and
put it inside the bracket in quotes. The same issue happened,

I then just tried putting in the action web page/method that calls it and used the stream method as follows:
(The directory under the web site tht I write files to, so it is not a permissions issue of access.)
Dim oStream As Stream = File.OpenRead(HttpContext.Current.Server.MapPath("FaxReports") & "\" & "license.elic.xml")
Spire.License.LicenseProvider.SetLicenseFileStream(oStream) The same issue happened,

I then tried putting the following code in the routine that calls the dll to create an excel spreadsheet: The code is:
Dim licenseFile As New FileInfo(HttpContext.Current.Server.MapPath("FaxReports") & "\" & "license.elic.xml")
Spire.License.LicenseProvider.SetLicenseFile(licenseFile) The same issue happened,

It still gives me the evaluation tab and only 5 actual tabs.

What should I do?

I am using Windows 7 Pro 64 and Microisoft Visual Studio 2019, asp.net/vb.net code base
