I'm trying since yesterday to download the latest component pack version (8.1.3.0) but I 've got a file of 63.9MB instead of 77.02MB. It's the second attempt this morning and still the same issue.
If I try to unzip the archive, 7z and Winrar are not able to open it.
As there is the security limitation of 1 download per day, it's quite complicated if you have a corrupted file to retry the download.
The download counter has been reset. You should be able to download again.
If you encounter any issue, you can always contact us to reset it.
I'd suggest to delete all downloaded files and retry the download or try to download on a different machine. Please make sure there is no firewall or antivirus software interfering with the internet connection while downloading.
