Unable to ugrade the RSS 4000. At time of upgrading it's showing an error " Invalid package file". we have try with different version 8.0, 8.5, 8.5.3, change the laptop from where we r try to upgrade. Even connect direct cable between RSS and Laptop. But problem remain same.
needs help to resolve the issue.
I am experiencing the same issue. Does anyone have a fix for this? Doe it have anything to do with the version of IE that I am using?
IE is usually your best bet when it comes to upgrades but Chrome also works well. The key is to make sure you are using the 32-bit version of the browser. the 64-bit versions frequently cause problems.
