Ok. Really interesting....... Just checked the Windows update history in case something happened here. The only update listed was a Windows Defender Definition update. The only difference between the two windows systems are: The server is Running with Windows 10 Pro 1503 and the remote Client uses Windows 10 Pro 1803. I'll keep an eye on this. If it reoccurs, I'll open a new forum topic. Now that I have the client installed on both systems, I can test this too. But thanks for your support to find the cause. From my side the topic can be closed for now.

Hello, Sorry, I didn't had time before today, to run the test with a locally installed EFB Client. With the latest EFB server and client update it is working locally and remote. Looks like you found the issue.

I copied the ZIP file from the Server's computer manually to the Client. On the Client I extracted the ZIP file without issues and the bin-File could be loaded. Maybe the Windows Explorer uncompress ignores an error in the ZIP without telling me, but I have my doubts. I can try installing the Client on the Server side and test, if the issue occurs also on the Server's side. Hopefully I have some time the evening.

I don't think it is the transfer. If I copy the ZIP manually and start the client, it shows the same error. It looks more like that something goes wrong with the unzip part in the client.

Good morning, I'm not sure, if I shall open a new topic for the same issue or not. I have to report the same issue but with the a licensed version. Here the snippet of the Logfile: 2018-07-25 08:37:17.891 Debug : Files to sync 7 2018-07-25 08:37:29.223 Debug : Creating file 'airports.bin' 2018-07-25 08:37:29.412 Debug : Decompress file 'airports.bin.zip' 2018-07-25 08:37:29.466 Error : Cannot read that as a ZipFile Ionic.Zip.BadReadException: Bad signature (0x00080000) at position 0x0222E9F9 at Ionic.Zip.ZipEntry.ReadDirEntry(ZipFile zf, Dictionary`2 previouslySeen) at Ionic.Zip.ZipFile.ReadCentralDirectory(ZipFile zf) at Ionic.Zip.ZipFile.ReadIntoInstance(ZipFile zf) at Ionic.Zip.ZipFile.ReadIntoInstance(ZipFile zf) at Ionic.Zip.ZipFile.Read(String fileName, TextWriter statusMessageWriter, Encoding encoding, EventHandler`1 readProgress) at e.v.d.m.e(String A_0) at e.e.v.eb.v.eg1(Byte[] A_0) 2018-07-25 08:37:29.484 Error : Unable to read beyond the end of the stream. at System.IO.__Error.EndOfFile() at System.IO.MemoryStream.InternalReadInt32() at e.e.v.eb.d.egy(Byte[] A_0) Server and Client are running on different systems. I tried a manual unzip with WinRAR on the server side and this works. The same on the client side (Windows 10 build in uncompress in the WinExplorer). If I extract the ZIP and place the bin file manually, then I'm able to start the client properly.
