RapidStart Services are introduced in Dynamics NAV 2013 as a mean of quickly setting up a new company with predefined data. It has great benefits for NAV implementers when working with new clients or setting up new company in test environment.
While working on localization of NAV 2013 for Serbia we started having problems with importing Rapidstart package files. The error we got, while testing, was “The specified file could not be imported because it is not a valid RapidStart package file.
We have found out that the problem was in Codeunit 8619 Config. Pckg. Compression Mgt. The function IsGZip did not return true in our case, although the file was created with the same database for NAV 2013.
The source of the problem was that the Windows Server, on which our NAV Server was installed, had Regional Settings for Language for non-Unicode programs set to “Serbian (Latin, Serbia and Montenegro (Former))”.
So we had two options to resolve the error.
This was simple as setting the Regional Settings for Language for non-Unicode programs set back to English (United States). After restarting the Windows Server the error was gone. I would recommend this solution wherever this setting does not interfere with other software installed on NAV Server.
This solution is “not the best option” but it is focused on changing the IsGZip function in Codeunit 8619 Config. Pckg. Compression Mgt. so it returns TRUE after uploading file to NAV Server. I would not recommend this solution but if there are no other options then…
