If you have a license for an older version and do not want to update it, you can find your old StrePla version here. Which version fits to your license key you can see from the release date. If the release date is within the time range of your purchase date plus one year, then this is your version.
Please note that rule changes are naturally not reflected in the old versions. Please do not use these versions to report flights to the OLC.
We strongly advise against using versions of desktop*StrePla older than version 7. With version 7 we have changed to a secure, encrypted connection between your desktop*StrePla and our server. With the older versions it cannot be ensured that you download malware.
