We have a legacy app using xceedftp and xceedzip. The zip function is working fine. However, on some windows 10 machines, we are getting a license key missing or invalid when being called. The same code will work on other machines, and windows 7 machines. The xceed zip functions continue to work even on the machines that the ftp is not.
the license key is including in the call in the executable.
You are using Xceed Zip for ActiveX and Xceed Ftp for ActiveX, is that right?
If so, are you sure that the XceedZip.dll and XceedFtp.dll files have been registered on the target machines with regsvr32.exe?
Another question. Is your application a 32-bit application? Please note that Xceed Ftp for ActiveX is compiled for 32-bit applications only. Xceed Zip for ActiveX is 32-bit only also, but we do have a 64-bit version, Xceed Zip for x64, that can be purchased separately.
