Updating MinimServer from 0.8.3 to 0.8.4 on ReadyNas

[simoncn]

The installation should work after removing 0.8.3 but I suppose there is the possibility that something went wrong with the removal.

Have you checked the length of the file you are uploading? It should be 1972224 bytes long. From the error message, it looks like there is a problem with the 0.8.4 package file that was uploaded to the NAS.

You could try downloading the file again and/or using a different browser for the upload to the NAS.
