Please provide ‘non-installer’ downloads for your products (as you have in the past) since I can now not install the latest versions.
I do not have Administrator rights on my work PC, so I have no way to get to the unpacked assemblies.
Hi,
Thanks for using Aspose.Cells.
Please download the ZIP file instead of MSI from here.
https://downloads.aspose.com/cells/net/new-releases/aspose.cells-for-.net-17.5-(dlls-only)/Let us know if you still face any issue. We will look into it and help you asap.
FYI:
From this link, you can access all the .NET versions most recent as well as previous ones in MSI and ZIP formats.
Thanx, that worked for me,
though it is not very intuitive you’d have to navigate to the actual ‘net’ folder in order to see the other dowload options (yyy/words/net vs. yyy/words/).
Or maybe I am just getting old.
Hi,
Thanks for your cheerfulness and using Aspose.Cells.

Some More Information:
Earlier, Aspose APIs have individual naming schemes which do not match with each other. Like, Aspose.Cells has different version number and Aspose.Words has different version and so on.
But now, we follow this naming scheme
YY.M (Year and Month)
17.5 (This means 2017-May)
17.6 (This means 2017-June)
17.7 (This means 2017-July)
Next Year it will be like
18.1 (This means 2018-Jan)
18.2 (This means 2018-Feb)
In short, now all Aspose APIs will follow this naming scheme. i.e. YY.M.
