Installing TAGRA

No. If Firebird or the Microsoft Windows Desktop Runtime is already installed on your PC (for example from a previous TAGRA installation or a Windows update), untick the corresponding box in the installer and it will be skipped.

Yes. Choose the “Offline” option on first launch instead of “Try” or “Activate”. It generates an offline license file tied to that specific PC, which you can then activate without a live internet connection.

TAGRA stops opening until you either purchase a license (via the “Renew” button) or activate a purchased license number and activation code. No data you've already downloaded or evaluated is lost.

You choose the database location yourself during first login — we recommend your Documents folder. The database is a single .fdb file (for example tagradb.fdb), so it can be backed up or moved like any other file; just reconnect TAGRA to the new path afterwards.

Email helpdesk@tagra.app and our technical support team will help you get unstuck — see the “Need a hand?” box at the end of this guide.

TAGRA is specialized software for evaluating and archiving data from digital tachographs and driver cards. It helps transport operators meet legal obligations under EU Regulation 561/2006, the AETR agreement and working-time law — checking driving times, breaks and rest periods, generating reports, and archiving data in .DDD format.

It depends on your fleet: TAGRA TRUCKER for a single driver evaluating just their own card, TAGRA 1 for one vehicle, TAGRA 2/4/6 for small to mid-size fleets, and TAGRA MAX for unlimited vehicles. TAGRA TRUCKER EDU suits driving schools with unlimited driver cards. As your fleet grows, your license can be upgraded without buying the software again — see the full comparison on our fleet operators page.

The first year of updates is included in the purchase price. From the second year, an annual license fee applies depending on the variant: from €19/year (TAGRA Trucker) up to €139/year (TAGRA MAX), covering both legislative updates and technical support — see the full pricing table.

Driver card data must be downloaded at least every 28 days, and vehicle tachograph data at least every 90 days, under EU Commission Regulation 581/2010. Downloaded data must then be archived for at least one year — we recommend 3–5 years.

Downloading alone only satisfies the archiving requirement. Article 10(2) of EU Regulation 561/2006 also requires operators to regularly check the data and address driver violations — which is exactly what TAGRA does, clearly flagging violations and preparing reports for inspections.

Yes. TAGRA is fully compatible with second-generation smart tachographs (G2V2) and supports both VDO and Stoneridge units, working with .DDD (card/vehicle), C1B and V1B formats.

TAGRA TRUCKER evaluates only driver card data — one driver, one card. TAGRA 1 additionally evaluates vehicle tachograph data, making it the right choice for owner-operators with a single vehicle who need full operator-level compliance, not just their own driving record.

TAGRA is a native Windows application. On a Mac, you can run it via Parallels Desktop, VMware Fusion, or Remote Desktop to a Windows server — but for the best stability and performance, we recommend a PC running Windows 10 or 11.

The standard license is single-user (one computer, one user). A networked, multi-user variant is available for teams that need shared access — contact sales@tagra.app to discuss pricing and setup.

TAGRA reads the standard .DDD, C1B and V1B formats used across all tachographs and download devices, so data from another brand's download key loads and evaluates without any problem. You don't need to switch hardware — just start evaluating in TAGRA.

Yes. From 1 July 2026, the tachograph and data-evaluation obligation extends to vans and combinations of 2.5–3.5 t used in international transport for hire or reward, or for cabotage. TAGRA is fully ready for this change. Read more in our guide on the new obligation.

Yes — we offer hands-on training on using TAGRA for your team, and technical support (phone, email and remote assistance) is included for the full duration of your license.

You can use our evaluation service instead — send us your data and our specialists handle the violation checks, reports and summaries for you. It's a good fit for operators who'd rather not handle evaluation in-house. Contact sales@tagra.app to discuss.
